Calculate Your Desk Sharing Ratio

Calculate your Desk Sharing Ratio—formula, free calculator, industry benchmarks, cost savings, and pitfalls to avoid.

Desk Sharing Ratio

You pay thousands of euros in rent every month for office space, yet half the desks sit empty each day while your team complains about too few meeting rooms, missing quiet zones or insufficient collaboration areas. The solution lies in correctly calculating the Desk Sharing Ratio—a simple key figure that shows how to repurpose existing space intelligently. In this article you’ll learn how to calculate the ratio for your industry, which benchmarks other companies use and what insights and measures you can derive.

What Is the Desk Sharing Ratio?

The Desk Sharing Ratio expresses the relationship between available workstations and your total number of employees.

Example: You have 100 employees and 70 desks. Your Desk Sharing Ratio is 0.7.

That means 1.43 employees share each workstation, or put differently: not everyone can be in the office at the same time.

  • Desk Sharing Ratio Below 1.0: Fewer desks than employees (true desk sharing)
  • Desk Sharing Ratio Exactly 1.0: Traditional model, one desk per employee
  • Desk Sharing Ratio Above 1.0: More desks than employees (oversupply—e.g., with coworking or guest desks)

The ratio helps you make three essential decisions: you see whether your current office space is optimally used, you can calculate how much space you really need when expanding or relocating, and you gain an objective basis for discussions with management about space costs.

Difference: Desk Sharing Ratio vs. Utilisation Rate

Do not confuse the Desk Sharing Ratio with the utilisation rate, which measures how often the available desks are actually used. The Desk Sharing Ratio is a planning value; the utilisation rate is a measurement value.

Application of the Desk Sharing Ratio

  • Space planning and cost control: With the ratio you calculate exactly how much office space you need when changing buildings. Example: An IT company with 200 employees moves offices and reduces its ratio from 1.0 to 0.7. The new space can therefore be 30 % smaller.
  • Repurposing space: Identify unused desks and convert them into meeting rooms, quiet zones or creative areas. Instead of 20 empty desks you could create an extra meeting room and a lounge for your team.
  • Growth planning: When your company grows you do not need to rent proportionally more space. With a ratio of 0.8 you can accommodate 25 % more employees without moving.
  • Decision basis: The ratio replaces gut feeling with facts—especially helpful in negotiations with management, the works council or during budgeting.

The basic formula gives you a figure that shows the bare facts. For planning office space or restructurings it is extended to show the number of required desks.

Step 1: Determine Employee Count

Count all employees who could in principle need a workstation, including full-time and part-time staff, working students and external consultants who regularly work on-site. For interns you can use a lump sum value.

Step 2: Analyse Attendance Patterns

Find out how often your employees are actually in the office. A meaningful survey requires a longer period that balances cyclical differences—mainly weekday effects and monthly rhythm. Ideally, carry it out outside holiday periods and seasonal peaks. In general: the longer the observation period, the more reliable the numbers.

Typical reasons for absence:

  • Home office (usually 2–3 days per week)
  • Vacation (around 25–30 days per year)
  • Sickness (about 15 days per year)
  • Business travel and client appointments
  • Training and conferences

Example: Your employees are on-site 60 % of the time on average. With 100 employees you theoretically need 60 desks.

Step 3: Add a Safety Buffer

Without a buffer the office can quickly become crowded. We recommend 10–15 % extra desks for:

  • Team days or all-hands meetings
  • Fluctuations during the year
  • Onboarding new employees

Example continued: 100 employees × 60 % = 60 desks. With a 15 % buffer: 60 × 1.15 = 69 desks. Your Desk Sharing Ratio is then 0.69.

Practical Calculation Examples

IT start-up
With 50 employees who are on-site 60 % of the time (≈ three home-office days per week) and a 15 % safety buffer, the company needs 35 desks, giving a Desk Sharing Ratio of 0.70.

Consulting firm
A workforce of 100 employees, an on-site rate of 40 % because of intensive client work and a 10 % buffer means 44 desks are required, resulting in a ratio of 0.44.

Financial services
For 80 employees with an on-site rate of 85 % (little home-office) and a 10 % buffer, 75 desks are needed, which equates to a ratio of 0.94.

Desk Sharing Ratios by Industry

IT & Tech Companies

Recommended ratio: 0.6 – 0.8

Tech firms are pioneers of flexible work. Developers often focus at home but come to the office for sprints and pair programming. A software company with 120 developers manages with a ratio of 0.65; staff are on-site only 2.5 days per week on average.

Financial Services

Recommended ratio: 0.8 – 0.9

Banks and insurers are more cautious. Compliance requirements, confidential customer data and a more traditional culture keep home-office rates lower. Example: A regional bank starts at 0.85 and lowers to 0.78 after one year. Certain workstations require special IT security; customer advisory work is mainly on-site; regulators sometimes require everyone in the office at short notice.

Consulting & Professional Services

Recommended ratio: 0.4 – 0.7

Consultants work mainly at client sites. Example: An international consultancy has 200 consultants but only 90 desks, giving a ratio of 0.45—possible because 70 % of time is spent at clients. There are extreme fluctuations; in holiday season the office can be empty, before proposal deadlines every desk is occupied. Only a booking system ensures that a desk is available after travelling to the office.

Marketing & Creative Agencies

Recommended ratio: 0.6 – 0.8

Creatives need inspiration from others but also like focused solo work. A digital agency with 60 employees runs a ratio of 0.7, providing enough space for spontaneous brainstorming yet flexibility for home-office. Creative rooms and presentation areas are additionally needed; freelancer attendance varies greatly.

Guide: Applying the Desk Sharing Ratio Company-Wide

Phase 1: Analysis and Data Collection

  • Count all usable desks and document their equipment (e.g., dual monitors, laptop dock).
  • Measure attendance for at least a month using an Excel sheet, time-tracking system or badge data—ensure no individual behaviours can be identified later.
  • Survey employees anonymously (5–6 questions) on home-office frequency, client appointments and desk preferences.

Phase 2: Calculate Ratios and Develop Scenarios

Use your data and the formulas. Typical reference scenarios:

  • Conservative (0.9): Minimal risk, low savings—good starting point.
  • Moderate (0.7): Balanced efficiency and comfort—often ideal.
  • Very progressive (0.5): Maximum efficiency, higher risk of too few desks—only for highly flexible models.

For each scenario calculate cost savings if you moved into smaller premises, including rent, utilities, cleaning and IT.

Phase 3: Prepare Change Management

  • Inform the works council from the outset; desk sharing is often subject to co-determination.
  • Identify supporters in each department and make them change ambassadors.

Phase 4: Run a Pilot

  • Start small—choose a receptive department or floor (IT or Marketing).
  • Define measurable goals: desk utilisation, employee satisfaction, issues.
  • Hold weekly feedback sessions.
  • Provide identical equipment at every desk; introduce a booking system if > 20 employees.

Phase 5: Roll-out and Optimisation (8–12 weeks)

  • Expand gradually—allocate 2–3 weeks per department.
  • Continuously optimise based on data: which desks are never booked, where are bottlenecks, which teams need closer proximity?
  • Adjust the ratio after three months—the initial phase often shows you can plan more boldly or conservatively than expected.

Common Mistakes in Handling the Desk Sharing Ratio

The six most frequent mistakes when dealing with the Desk Sharing Ratio are overly aggressive ratios, physical separation of teams, inconsistent IT equipment, lack of communication, static ratios without adjustment, and ignored legal aspects.

Mistake 1: An Overly Aggressive Ratio from the Start

You think: “If 0.7 is good, 0.5 must be even better.” The outcome: employees have to reserve a workstation far in advance to secure one. Trust in desk availability decreases, and fewer people choose to work on-site. This solves the scarcity problem but unnecessarily pushes staff into home office and creates a feeling of not being welcome.

Solution: Start conservatively at 0.8 and reduce gradually. Better to have a little too much space for six months than two weeks of overcrowding.

Mistake 2: Teams Are Physically Torn Apart

Desk sharing does not mean everyone has to sit randomly. If the marketing team is spread over three floors, collaboration suffers.

Solution: Define team areas. Reserve a fixed zone for each department with 70–80 % of the theoretically required desks. Teams can sit together without everyone needing a fixed seat. Also plan regular team days when all members are on-site.

Mistake 3: Insufficient Technical Preparation

If employees arrive at their booked desk and find the wrong equipment, they are understandably frustrated and cannot start working.

Solution: Rigorously standardise equipment. Every workstation needs identical technology: same monitors, keyboards and docking stations. Invest in a robust cloud infrastructure. Employees must be able to access all required systems from any desk.

Mistake 4: Lack of Communication and Change Management

You announce the new system via email and are surprised by the pushback. Employees fear losing their familiar spot, fail to see the benefits or feel bypassed.

Solution: Communicate early, openly and continuously. Explain not just the “what” but especially the “why.” Hold workshops, answer questions, gather feedback.

Mistake 5: Static Ratio without Monitoring

You calculate the ratio once and leave it unchanged for three years. Meanwhile, everyone works more from home, yet you still have too many workstations.

Solution: Review the ratio quarterly. Examine utilisation data, survey employees, analyse booking patterns.

Mistake 6: Neglecting Legal Aspects

You ignore company agreements, forget the works council or overlook workplace regulations. This can bring the entire project to a halt.

Solution: Inform the works council from the outset and involve it in planning. Check existing company agreements for rules on fixed desks. Ensure all ergonomic and safety standards are met—especially those in the workplace ordinance.

Software for Implementing the Desk Sharing Ratio 

Desk sharing requires three capabilities: capturing actual attendance, booking desks after introduction and continuous monitoring of booking behaviour. PULT covers all three.

Automatic Attendance Detection for the Planning Phase 

PULT Presence logs attendance automatically: as soon as an employee’s smartphone or laptop connects to the corporate Wi-Fi, they are marked present—no manual action, no forgetting. Zero-click works with your existing WLAN infrastructure (HPE Aruba, Cisco, Ubiquiti, etc.). After two to four weeks you know exact utilisation and can calculate your ratio reliably.

Desk Booking without Re-Learning 

PULT integrates directly into Slack, Teams and Outlook. Employees book a desk with one click in the tools they already use—no extra app, no new passwords. The booking plan mirrors your office and shows all available desks with features (standing desk, dual monitors, next to a favourite colleague). Filters help find the right spot fast.

Continuous Optimisation of the Desk Sharing Ratio 

PULT Analytics displays average utilisation of desks, zones and rooms per day and week, popular and unpopular desks, and booking behaviour by team. With booking and attendance data you always see your ratio. If overcapacity persists you can either

  • gradually remove desks and repurpose freed space (quiet zones, gym, etc.), or
  • intensify your back-to-office strategy to bring more employees from home office to the office.

FAQ

Have questions?

How often should the ratio be reviewed?

Review it quarterly based on actual utilisation data. Adjust more often after new home-office rules or rapid growth.

What happens if too many employees come to the office at once?

Plan a safety buffer of 10–15 %. You can also designate zones that can be quickly converted into desks if needed.

Is the ratio calculated differently for part-time employees?

Yes—count part-timers proportionally (a 50 % employee counts as 0.5). For the Desk Sharing Ratio, actual attendance is more important than the contract model.

Can I use different ratios for different departments?

Yes - e.g. IT support or help-desk staff may be in the office more often than sales. Calculate ratios per department and plan corresponding areas in the office.

Is a Desk Sharing Ratio of 0.5 realistic?

A ratio of 0.5 is realistic only for companies with extremely high home-office rates or extensive field service, such as consultancies. For most organisations it is too aggressive.

Workplace Safety in the Office: Legal Obligations, Ergonomics and Prevention

Workplace safety in the office serves to maintain employee health and provide legal protection for employers. In modern hybrid offices, safety places new demands on the organization of desk sharing and mobile work.

Workplace Safety in the Office: Key Takeaways

  • Legal framework for workplace safety in the office: The foundation consists of the Occupational Safety Act (ArbSchG), the Workplace Ordinance (ArbStättV) and DGUV Information 215-410.
  • Risk assessment in the office: The employer must identify and document the risks (physical and psychological) for each workplace.
  • Ergonomics: Desks, chairs and monitors must be adjustable to prevent musculoskeletal disorders.
  • Personnel: Depending on company size, safety officers, first aiders and fire safety assistants must be appointed in the required numbers.
  • Safety briefings: At least once a year, all employees must be instructed on the hazards and protective measures in the workplace.

What legal regulations apply to workplace safety in the office?

Workplace safety in the office is primarily governed by the Occupational Safety Act (ArbSchG) and the Workplace Ordinance (ArbStättV), which are further specified by DGUV Information 215-410.

These regulations require employers to systematically assess hazards, comply with technical standards for computer workstations and ensure employee safety through regular briefings and the provision of first aiders.

  • Occupational Safety Act (ArbSchG): It forms the foundation and obliges the employer under § 5 to conduct a risk assessment. The goal is to design work in such a way that hazards to life and physical and mental health are avoided.
  • Workplace Ordinance (ArbStättV): It defines minimum requirements for the operation of workplaces. This includes aspects such as room temperature, ventilation, lighting and the design of computer workstations.
  • DGUV Information 215-410 (formerly BGI 650): This guideline from the German Social Accident Insurance is the most important practical standard for offices. It contains detailed requirements for ergonomics, floor space and the safety-related design of work equipment.
  • Display Screen Equipment Regulation (now part of ArbStättV): It sets specific requirements for the quality of monitors, keyboards and software ergonomics to prevent strain on the eyes and musculoskeletal system.

Responsibility and Implementation of Workplace Safety in the Office

The employer is solely responsible for compliance with and implementation of all measures. For support, from the very first employee, the employer is required to provide proof of safety engineering and occupational health care (according to ASIG and DGUV Regulation 2).

Occupational safety specialists (Sifa) and company physicians provide advisory services, but keeping escape routes clear or correctly adjusting office furniture falls under the responsibility of the respective managers or office management.

How is a risk assessment created for office workplaces?

The risk assessment is the required tool for identifying risks to employee health and initiating countermeasures. According to § 5 of the Occupational Safety Act, every employer is obliged to conduct this assessment for all workplaces, document it and update it regularly.

  1. Define work areas: Divide the office into meaningful units, for example individual offices, open spaces, meeting rooms.
  2. Identify hazards: Record all physical and psychological stresses.
  3. Assess hazards: Evaluate the risk (probability of occurrence and severity of potential damage).
  4. Define protective measures: Select appropriate measures according to the TOP principle (Technical before Organizational before Personal).
  5. Implement measures: Carry out the planned improvements.
  6. Check effectiveness: Verify whether the measures have actually reduced the risk.
  7. Document and update: Legally compliant documentation of results and adaptation when changes occur (e.g. new office furniture or software).

Consideration of Psychological Stress in the Office

Since 2013, the Occupational Safety Act has explicitly required that the psychological risk assessment must also be part of the process. In the office, the focus is on factors such as work intensification, constant availability, lack of recovery periods or inadequate work organization. The goal is the prevention of stress-related illnesses and burnout.

Special Case: Risk Assessment for Hybrid Work (Office/Home Office)

Due to the alternation between office and home office, the assessment must extend beyond time spent in the office. The employer must also consider hazards for working from home and on the go. Since the employer has no direct right of inspection in the private space of employees, this is done through self-assessment questionnaires and instructions for the ergonomic design of the home workplace.

What ergonomic requirements must office workplaces meet?

Workplace ergonomics aims to adapt working conditions to the physical characteristics of people. The overarching goal is to prevent improper strain and chronic musculoskeletal disorders .

DGUV Information 215-410 and the standards DIN EN 527-1 (desks) and DIN EN 1335 (office chairs) define exact minimum requirements for this purpose.

The Ergonomic Office Chair

A suitable chair must allow dynamic sitting and be individually adjustable:

  • Seat height: The thighs should slope slightly downward, with feet flat on the floor (knee angle approx. 90° or slightly more).
  • Backrest: It must have lumbar support that supports the natural curvature of the spine in the lower back area.
  • Dynamics: The backrest should be movable (synchronous mechanism) to encourage alternating between leaning forward and backward.

The Office Desk

The desk must provide sufficient space for work equipment and the correct working height:

  • Dimensions: The standard surface area is 160 x 80 cm. A depth of at least 80 cm is necessary to maintain the viewing distance to the monitor.
  • Height: For fixed desks, the standard measurement is 74 cm (± 2 cm). However, height-adjustable sit-stand desks (switching between 65 cm and 125 cm) are ideal for reducing cardiovascular strain.
  • Surface: It must be low-reflection and matte to avoid glare from light sources.

Monitor and Input Devices for the Office

The placement of technology affects the strain on neck and eyes:

  • Viewing distance: Depending on monitor size, this should be between 50 cm and 70 cm.
  • Viewing angle: The top line on the screen should be well below eye level, so that the gaze is slightly tilted downward.
  • Arrangement: The monitor must be positioned directly in front of the user (no twisted posture). Keyboard and mouse should be placed so that the forearms can rest relaxed on the desk.

Light, Noise and Climate in the Office

  • Lighting: For office work, an illuminance of at least 500 lux is required. Natural daylight is preferred, while glare must be prevented using blinds.
  • Noise: The sound pressure level should not exceed 55 dB(A) for predominantly mental tasks.
  • Indoor climate: The recommended room temperature is between 20°C and 22°C. The relative humidity should be between 40% and 60%.

How many first aiders and safety officers do I need for the office?

The number of persons to be appointed for occupational safety is legally defined and depends on the number of insured persons present in the workplace according to DGUV Regulation 1.

  • First aiders: In offices with up to 20 employees present, one first aider must be appointed. From 21 employees onwards, at least 5% of the workforce must be trained as first aiders.
  • Safety officers (SiBe): From a company size of 20 employees, the appointment of at least one safety officer is mandatory. They support the employer on a voluntary basis in accident prevention.
  • Fire safety assistants: Here too, a quota of typically 5% of employees applies. Find all details about training and equipment for fire safety in the office.

Important for planning: The employer must ensure through vacation and sick leave periods as well as hybrid work models that the required number of helpers are physically present in the office at all times.

How is workplace safety implemented in the office with desk sharing and hybrid work?

The introduction of work models such as desk sharing and hybrid work fundamentally changes the requirements for occupational safety. Companies must ensure that the protection goals of the Workplace Ordinance (ArbStättV) are also achieved with daily user changes and in the home office.

  • Ergonomics: Since every employee has different physical requirements, shared workplaces (shared desks) must be versatile and easily adjustable.
  • Space utilization and capacities: In open-space concepts, there is a risk of overcrowding, which increases noise levels and can undermine escape route concepts.
  • Psychological stress: The uncertainty of not finding an adequate workplace in the morning ("desk hunting") creates additional stress and reduces concentration.
  • Hygiene: Frequent user changes require hygiene rules and adapted cleaning cycles.

How does booking software help with workplace safety and health in the office?

PULT is our software for workplace and room booking as well as automated presence detection. It serves many employers as a platform to fulfill their duty of care. The software includes features for ergonomics, emergency management and health protection:

  • Equipment filter: Employees can specifically search for workplaces with height-adjustable desks (sit-stand desks), ergonomic chairs or special monitors.
  • Fixed assignments when needed: For employees with special medical or physical requirements, PULT enables permanent reservation of fixed workplaces as an exception to desk sharing.
  • Emergency Export: At the push of a button, administrators generate a list of all persons actually present. Thanks to WiFi detection (PULT Presence), "no-shows" or spontaneous visitors are also precisely recorded.
  • Capacity control: The software automatically prevents overcrowding of zones. This way, fire safety regulations and escape route capacities are technically accounted for.
  • AI Health & Safety Agent: Our AI agent helps convert occupational safety regulations into tasks and pre-fill compliance documents for audits with real presence data.
  • Noise and acoustic management: Through clear zoning into quiet and team zones as well as the bookability of phone booths, acoustic stress is reduced.
  • Psychological relief: The guarantee of a firmly reserved workplace eliminates the stress of morning searching and ensures a calm start to the workday.

Fire safety in the office
Office Insights

Fire Safety in the Office – Regulations, Equipment, Checklist

Fire safety in the office is a legal obligation for employers. Compliance with workplace rule ASR A2.2, regular team briefings and the training of fire safety assistants are essential for responding quickly in an emergency.

Fire safety in the office: Key facts at a glance

  • Fire safety in the office is primarily governed by the Occupational Health and Safety Act (ArbSchG) and the technical rule ASR A2.2.
  • Fire safety equipment: The number and type of fire extinguishers depends on the floor area and fire risk (usually "normal risk" in offices).
  • Fire safety assistants: At least 5% of employees must be designated and trained as fire safety assistants.
  • Fire safety briefing: All employees must be instructed at least once a year on how to behave in the event of a fire and on escape routes.
  • Maintenance: Fire extinguishers must be inspected by a qualified person every two years; fire doors and alarm systems are subject to shorter intervals.

What regulations apply to fire safety in the office?

Fire safety in the office in Germany is primarily regulated by the Occupational Health and Safety Act (ArbSchG), the Workplace Ordinance (ArbStättV) and, in more specific terms, by the Technical Rule for Workplaces ASR A2.2. These regulations oblige you as an employer to ensure adequate firefighting measures, establish evacuation procedures and train a sufficient number of employees as fire safety assistants.

  • Occupational Health and Safety Act (ArbSchG): According to § 10, the employer is obliged to take the measures necessary for first aid, firefighting and the evacuation of employees. They must designate the persons who will assume these tasks in an emergency.
  • Workplace Ordinance (ArbStättV): The annex (section 2.2) stipulates that workplaces must be equipped with fire extinguishing devices and that these, along with fire alarm systems, must be regularly tested for functionality.
  • ASR A2.2: This technical rule specifies the ArbStättV in detail. It provides exact requirements for the number of fire extinguishers needed (extinguishing agent units), the marking of escape routes and the training of fire safety assistants (usually 5% of the workforce).
  • DGUV Regulation 1: This accident prevention regulation of the employers' liability insurance associations requires regular instruction of all insured persons on the hazards present in the workplace and the measures to avert these hazards.

The overall responsibility for fire safety always lies with the employer. The landlord of a property is responsible for structural fire protection (e.g. fire doors, stairwells), while operational fire safety (e.g. fire extinguishers, briefings, assistant training) is the responsibility of the tenant company.

How is fire safety ensured in the office and workplace?

Fire safety in the office comprises structural, technical and organisational fire protection. Structural measures should be implemented by the building owner, but the responsibility for technical equipment and organisational procedures lies directly with the employer in the office.

Structural fire protection

This part of fire protection encompasses all measures permanently built into the building that prevent the spread of fire and secure rescue routes.

  • Fire compartments: Division of the building by fire walls.
  • Escape and rescue routes: Designation of stairwells and emergency exits that must remain smoke-free in the event of a fire.
  • Fire resistance classes: Use of materials that withstand fire for a defined period (e.g. F90).

Technical fire protection systems

This includes all technical installations that detect a fire early or support firefighting efforts.

  • Fire alarm systems (BMA): Automatic detection of smoke or heat and direct alerting of the fire brigade.
  • Smoke extraction systems (RWA): Extract smoke gases from the building to protect people and improve visibility for evacuation.
  • Emergency lighting: Ensures escape routes can be found in the event of a power failure or smoke.

Organisational fire protection

This is the area with the greatest need for action by office management, as it governs human behaviour and ongoing maintenance.

  • Fire safety regulations: Preparation of parts A, B and C to govern behaviour and responsibilities.
  • Fire safety assistants: Designation and training of employees for initial firefighting and evacuation.
  • Maintenance & inspection: Ensuring inspection deadlines for fire extinguishers, wall hydrants and alarm systems.
  • Briefings: Regular training of all employees on the specific hazards and escape routes in the office.

How many fire extinguishers does my office need?

The number of fire extinguishers required in an office depends on the floor area and fire risk, with normal risk generally assumed for standard administrative buildings. The extinguishing agent unit (LE) system according to workplace rule ASR A2.2 is used to determine the requirement, making the different performance levels of various extinguishing agents comparable.

Step 1: Determining the fire risk

Before calculating the number, the risk class must be determined:

  • Normal risk: Standard offices without high fire loads (e.g. ordinary computer workstations, files in usual quantities).
  • Elevated risk: Rooms with flammable liquids, large storage areas or workshops. Additional measures are required here.

Step 2: Calculating extinguishing agent units (LE)

For offices with normal risk, the following table from the technical rule for workplaces ASR A2.2 (section 5.2, table 3) applies for determining the required extinguishing agent units:

Floor area (up to m²) Required extinguishing agent units (LE)
50 6
100 9
200 12
300 15
400 18
each additional 250 +6

Step 3: Selecting the fire extinguishers

A standard 6-litre foam extinguisher usually corresponds to 6 to 9 LE (depending on performance). The choice of extinguishing agent is important in offices. Get advice from a fire safety company:

  • Foam extinguishers: They extinguish effectively and cause significantly less contamination than powder extinguishers.
  • CO2 extinguishers (carbon dioxide): Mandatory for server rooms or areas with extensive IT hardware, as they extinguish without residue and do not cause short circuits from extinguishing agent residues.
  • Powder extinguishers: Unsuitable for offices, as the fine salt powder permanently damages all electronics and furnishings (corrosion).

Important placement rules for fire extinguishers

  • Accessibility: Fire extinguishers must be clearly visible and easily accessible (maximum distance from any point: 20 metres).
  • Mounting height: The grip height should be approximately 80 cm to 120 cm.
  • Marking: Each location must be marked with the square, red fire safety sign (F001) above the extinguisher.

How many fire safety assistants must be designated for my office?

According to ASR A2.2 section 7.3, the employer is obliged to familiarise a sufficient number of employees with fire extinguishing equipment through instruction and practice and to designate them as fire safety assistants. These persons support initial firefighting and the evacuation of colleagues in an emergency.

  • The 5 percent rule: As a rule, 5% of employees as fire safety assistants is sufficient, provided there is a normal fire risk (which applies to most offices).
  • Attendance: Shift work, holidays, sick leave and mobile working (hybrid work) must be taken into account in the calculation. A sufficient number of assistants must be present on site at all times.
  • Special risk: In cases of elevated fire risk or a large number of persons with limited mobility (e.g. public traffic), the quota must be individually adjusted upwards.
  • Additional roles: It often makes sense to deploy fire safety assistants simultaneously as evacuation assistants to coordinate the building evacuation in a structured manner.

Fire safety assistant training and refresher courses

An employee only becomes a fire safety assistant through expert instruction. This includes:

  • Theoretical foundations: Fundamentals of preventive fire protection, behaviour in the event of fire and the operational fire safety organisation.
  • Practical exercise: Real-world handling of fire extinguishing equipment (extinguishing agent training).
  • Interval: Training should generally be refreshed every 3 to 5 years. In the event of significant operational changes (e.g. relocation or new procedures), immediate retraining is required.

What challenges does modern work pose for fire safety in the office?

The greatest challenge for fire safety in modern office concepts is the lack of overview of the actual number of people in the building, caused by hybrid work and desk sharing. Traditional, static attendance lists are ineffective in such a work environment, as employees appear irregularly, spontaneously switch workstations or leave the office without signing out.

  • In the event of an evacuation, rescue services need to know how many people are in which fire compartments. Paper lists or pure booking data (which often contain "no-shows") lead to life-threatening inaccuracies.
  • With free seating, there is a risk that too many people are in one area at the same time. This can overload escape routes or exceed the maximum permitted occupancy according to the fire safety concept.
  • As teams rotate, permanently assigned fire safety assistants per floor are often not present. It must be ensured that despite hybrid working, a sufficient proportion of trained personnel is always on site.

How do booking software and presence detection help with fire safety in the office?

PULT is our software for workspace and room booking as well as automated presence detection. Smartphones, tablets or laptops are detected via the company Wi-Fi and the associated person is automatically listed as present. This also creates a reliable attendance list for emergency situations.

Unlike pure booking systems, PULT detects the actual presence of employees, enabling precise coordination of evacuations and compliance with legal safety requirements.

  • Emergency report at the push of a button (Emergency Export): Administrators can instantly generate a list of all persons currently present in the office via a button. Since the system automatically detects presence via the Wi-Fi connection of devices, employees who forgot to book a desk are also captured.
  • Automated capacity limits: Maximum occupancy numbers per zone can be set in PULT's booking logic. This prevents overcrowding and ensures that fire safety concepts and escape route capacities are maintained at all times.
  • Vermeidung von Fehlern bei Evakuierungen: Die automatisierte Erfassung beendet das „Ratespiel“ am Sammelplatz. Rettungskräfte erhalten sofortige Klarheit darüber, ob das Gebäude vollständig geräumt ist oder ob sich noch Personen im Gefahrenbereich befinden könnten.

Toxic workplace: examples, test, and first steps for those affected

A toxic workplace causes lasting stress and has a negative impact on work performance and personal health. A toxic environment can be recognized, and there are ways out.

Toxic workplace: The most important facts in brief

  • A workplace is considered toxic when negative behavior patterns persist and do not improve despite warnings.
  • Typical characteristics of a toxic workplace include micromanagement, derogatory communication, withholding of information, overload, unequal treatment, and fear of repercussions.
  • The consequences of a toxic workplace include declining performance, ongoing stress, and long-term health risks.
  • Important countermeasures include documenting toxic situations in writing, setting boundaries, documentation, communication within the team, and, if necessary, involving the human resources department or works council.
  • Termination is appropriate when boundaries are consistently crossed and change is not achievable.
  • For a fresh start, platforms such as LinkedIn, Indeed, and local job portals offer a good overview of suitable positions.
  • Objective reviews on kununu or Glassdoor can warn others without incurring legal risks.

What is a toxic workplace? 

In a toxic workplace, recurring situations or behaviors noticeably impair the quality of work, personal well-being, or performance. 

A typical characteristic of a toxic workplace is that problems occur regularly, become entrenched, and are almost impossible to avoid in everyday working life. It becomes toxic when negative patterns persist and are difficult to improve. This does not refer to individual conflicts or high levels of stress.

Toxic work environment vs. stressful job

A stressful job is caused by a heavy workload or tight deadlines. Despite the pressure, cooperation usually remains predictable: agreements work, information is available, and criticism is possible. A toxic environment, on the other hand, is characterized by:

  • Constant uncertainty. You never know how the day will turn out.
  • Unreliable or contradictory communication.
  • Behavior that undermines respect or trust.
  • Problems that recur repeatedly, even after warnings or discussions.

12 characteristics and warning signs: How can I recognize a toxic workplace?

A toxic workplace is characterized by negative behavior patterns occurring regularly and permanently impairing cooperation. Typical signs include a lack of trust, derogatory communication, withholding of information, unfair treatment, constant overload, and unresolved conflicts. If several of these points exist at the same time and nothing improves despite warnings, it is usually a toxic workplace.

  • Micromanagement and lack of trust: The supervisor controls every step, constantly intervenes in details, and rarely allows independent decisions. Tasks take longer because approvals or queries are constantly required.
  • Unclear or conflicting expectations: Goals change at short notice, targets are vague or contradict previous statements.
  • Derogatory communication: Criticism is phrased in a personal manner, there is a lack of appreciation, and conversations are tense or conducted in a commanding tone. Suggestions or ideas are regularly dismissed or ignored.
  • Blame instead of problem solving: Mistakes are attributed to individuals, even if the causes lie in the process or the team. A constructive approach to problems does not develop.
  • Withholding information: Important information is deliberately delayed or not passed on. This makes it harder for those affected to do their jobs or makes them seem unprepared.
  • Clique formation and exclusion: Some members of the team receive benefits, access to supervisors, or informal information. Others are excluded, overlooked, or systematically isolated.
  • Frequent conflicts without lasting solutions: Points of contention regularly resurface because the underlying causes are not discussed. Conflicts tend to lead to distance or hostility rather than clear agreements.
  • Overwork as the norm: Workload, pace, or expectations are consistently higher than realistic. Breaks, relaxation, or adequate planning are rare. Overtime becomes the norm.
  • No recognition or appreciation: Successes are taken for granted. Feedback is rare or one-sidedly negative. Achievements are not acknowledged or are publicly belittled.
  • Unequal treatment: Rules do not apply equally to everyone. Some individuals receive special privileges, while others are judged more harshly. Decisions appear unfair or arbitrary.
  • Fear of reactions: Colleagues avoid addressing problems because they expect negative consequences. Criticism leads to sanctions, poorer treatment, or exclusion from decisions.
  • High turnover or frequent sick leave: Many leave within a short period of time or take sick leave.

How can I test whether my workplace is toxic?

The more of the following questions you answer Yes, the more likely it is that you have a toxic work environment:

• Am I heavily monitored in my work or frequently restricted in details?
• Do I often not know exactly what is expected of me or what the priorities are?
• Do I encounter derogatory comments, disrespectful language, or unnecessary harshness?
• Do I find that mistakes tend to lead to blame rather than solutions?
• Do I therefore tend to hide mistakes?
• Is important information being withheld or passed on late?
• Are there distinct cliques within the team; are individual people excluded?
• Do conflicts keep recurring without being resolved?
• Am I constantly overworked or regularly working beyond my limits?
• Do I rarely or never receive recognition for good work?
• Do I find it difficult to address problems openly because I expect negative consequences?

Classification:

These points will help you classify your initial assumption:

  • Do things improve if I address problems openly?
  • Do colleagues experience similar situations or stresses?
  • Do the patterns persist for weeks or months?

What can I do if my workplace is toxic?

In a toxic workplace, it helps to identify stressful situations, set clear boundaries, document incidents in writing, talk to colleagues, involve official bodies, and prepare possible alternatives.

  1. Describe situations: Describe stressful events: What happened? Who was involved? What impact did it have? 
  2. Set your own boundaries: Determine what behavior is acceptable to you and what is not. Keep these boundaries short and specific, for example: "I need clear instructions" or "I want to work without derogatory comments."
  3. Document events: Keep a factual record with dates, people involved, and situations.
  4. Seek allies: Talk to colleagues you trust. If similar observations are made repeatedly, this confirms the pattern and strengthens your position in discussions with supervisors or the human resources department.
  5. Involve official bodies: If discussions within the team are ineffective, seek advice from the human resources department, the works council, or another official body within the company. They will be able to assess what options and steps are available.
  6. Reduce your own stress: Ensure you get sufficient rest and relaxation, stick strictly to your working hours, and seek medical help if you experience symptoms such as sleep problems or constant exhaustion.
  7. Prepare an exit option: If no improvements are foreseeable, it makes sense to consider other options for your future career path. Update your resume, activate your network, and look into job opportunities. Being in a position to leave also strengthens your negotiating position internally.

Should I quit or stay in a toxic workplace?

Whether it makes sense to quit or stay depends on whether the stressful patterns can be changed or at least whether there is any sign of improvement. Quitting is advisable if your boundaries are constantly being crossed and internal attempts to find a solution have had no effect.

Criteria that speak in favor of a temporary stay:

  • There are specific areas for improvement.
  • Discussions with supervisors or the human resources department are proving effective.
  • The team offers you support and assists with necessary changes.
  • Stressful situations can be limited and become less frequent.
  • Your personal stability and resilience are still sufficient to wait out the coming changes.

Criteria that speak in favor of termination:

  • Despite discussions, your boundaries continue to be crossed.
  • Criticism leads to negative reactions or discrimination.
  • The leadership shows no interest in change.
  • The strain on your health is increasing, you are not getting any better in the long term, or you are even getting worse.
  • The toxic behavior is structurally embedded and affects many areas.

What happens next when a toxic workplace has no future?

If a workplace is permanently toxic and no realistic improvement is to be expected, then look ahead. On job portals, you can quickly find offers that broaden your horizons and show you that there are indeed other opportunities out there for you.

On LinkedIn, you can filter by company, industry, and working model. Indeed, StepStone, and similar platforms display a wide range of current job openings. It is also worth taking a regional look, for example via job portals of local newspapers, municipal career platforms, or company websites in your area.

Leaving a toxic employer often triggers strong emotions. Honestly examine whether you feel any desire for revenge. Openly disparaging, spreading rumors, or making negative statements about individuals or companies can have legal consequences, such as defamation. It is wise not to give in to these impulses and instead invest your energy in your own new beginning.

Nevertheless, you can protect others from problematic structures. An objective and accurate review on platforms such as kununu or Glassdoor is an effective way to expose abuses without attacking anyone personally. Stick to verifiable facts, describe working conditions, and avoid personal accusations. This will help other applicants while protecting your own position.

Tip: Never speak badly about former employers during job interviews, as this never goes down well. However, you can certainly mention that you had different ideas about what constitutes a healthy workplace and that this is why you are changing jobs. Your interviewer will appreciate statements of this kind.
