Assessing mental stress has been an express part of the risk assessment since 2013 (section 5 paragraph 3 number 6 ArbSchG). In office businesses it is often the most important hazard of all, because physical dangers are low. At the same time it is the part most often missing: a risk assessment without it counts as incomplete.
What mental stress means
The term is regularly misunderstood. What is assessed is not the mental state of individual employees but the conditions of work that affect everyone. This is about the work, not about diagnoses.
The distinction is also technically sound: stress is the demand acting from outside, strain is the individual reaction to it. What is assessed is the stress, because only that can be designed. Anyone surveying the reaction instead ends up at individual resilience, and that is the wrong track both legally and practically.
The five factor areas
The Joint German Occupational Safety Strategy (GDA) structures the topic into five areas. They also provide the structure for the survey.
- Work content and task: completeness of the task, scope for action, responsibility, qualification, emotional demands. Typical in an office: constant interruptions, and simultaneous over- and under-challenge in the same role.
- Work organisation: working time, workflow, communication. Typical: deadline pressure, unclear priorities, an expectation of availability beyond working hours, cover arrangements that do not work.
- Social relationships: leadership behaviour, cooperation in the team, handling conflict. Typical: missing feedback, unclear responsibilities, conflicts nobody picks up.
- Working environment: noise, crowding, disturbances, work equipment. In open-plan offices the most common point of all: acoustic disturbance and no quiet space for focused work.
- New forms of work: remote work, mobile working, desk sharing, constant availability through digital channels. In an office this is the area growing fastest, and the one missing from older assessments.
How the survey works in practice
The method is the same as for the rest of the risk assessment: identify, evaluate, decide measures, implement, review effectiveness, document. For the identification step there are three routes, which differ by business size.
- Written survey. Suitable from around 20 to 30 employees, because only then is anonymous evaluation possible. Advantage: reaches everyone, including the reticent. Disadvantage: produces numbers but no explanations.
- Facilitated workshops. Usually the better route in smaller businesses. A facilitated group works through the five factor areas and names concrete points. Advantage: produces starting points for measures directly. Disadvantage: needs a facilitator the group trusts.
- Structured observation and interviews. Supplementary, particularly for roles with public contact or shift work.
In practice a combination works well: a survey for the overview, then workshops in the areas with notable results, to understand what lies behind them.
Data protection and small teams
This is where most mistakes happen. The survey produces information that can be traceable to individuals, and that has to be prevented.
Two rules go a long way. First: present results only in aggregate and do not evaluate groups below a defined minimum size separately. Anyone reporting a four-person department on its own has not actually created anonymity. Second: no combination of attributes that allows identification, such as department, age and gender at the same time.
The occupational physician is a sensible partner here, because they bring the occupational-medicine perspective and are bound by confidentiality. More in The occupational physician in the office.
Measures that actually work in an office
The most common mistake after the survey is reaching for individual offerings: resilience training, a yoga class, a mindfulness app. That is not wrong, but it addresses the reaction rather than the stress itself. The hierarchy of controls in section 4 ArbSchG requires the opposite: change the conditions first, then behaviour.
Effective measures are mostly organisational and cost little:
- Put availability in writing: in which window a response is expected, and expressly that none is expected outside it.
- Reduce interruptions: focus times, rules for messaging channels, quiet space in open-plan areas.
- Clarify priorities: who decides what gets set aside first when too much arrives at once.
- Make cover arrangements binding, so that leave really is leave.
- Institutionalise feedback: regular short conversations instead of once a year.
- Improve acoustics in open-plan areas, see also Setting up a screen workstation correctly.
- Sharpen remote-work rules, because blurred boundaries occur there especially. See Remote work and telework.
A realistic sequence across a year
The assessment looks more demanding than it is. Spread across a year, a realistic sequence for an office business looks like this:
- Quarter 1: preparation. Settle works council involvement, choose the method, select the survey instrument, define the data protection rules (minimum group size, which attributes are not combined). Announce it internally with a clear statement of purpose and anonymity.
- Quarter 2: the survey. Questionnaire or workshops, depending on size. Wait for responses, evaluate, prepare results in aggregate.
- Quarter 3: feedback and measures. Report results back to the workforce; this is the step that determines credibility. Then decide measures, with an owner and a deadline, and document them in the risk assessment.
- Quarter 4: implementation and effectiveness review. Implement the measures, report status to the occupational safety committee, review effectiveness and record the result.
The effort therefore amounts to a few days a year spread across four quarters. What it does not tolerate is a survey without feedback: anyone who is asked and never learns the outcome will not take part next time.
What the survey cannot deliver
Realistic expectations are part of making this work. The risk assessment of mental stress is an occupational safety instrument, not a tool of people development and not conflict mediation.
It can show that interruptions make work harder, that unclear priorities create pressure, or that acoustics in an open-plan office prevent focused work. It cannot resolve a conflict between two people, shrink an overloaded organisation back to health, or substitute for leadership. Where such topics surface, they belong in the appropriate channel, not in the measures list of the risk assessment.
Why this part is so often missing
It feels soft, it is uncomfortable, and it has no obvious end point. So it gets deferred while the technical items are worked through. During an inspection that is exactly what stands out, because it is the easiest shortcoming to check: either the section exists in the documentation or it does not.
There is also a concern that is rarely spoken aloud: that a survey will make visible conflicts one would rather not see. That is understandable, but the calculation does not work. The stress exists regardless of whether it was surveyed, and it shows up later in turnover and absence days. The open points you can see with the duties quick-check and the office safety checklist mark the cheaper moment.
If an enquiry from the employers' liability insurance association arrives, this section is among the first to be asked about.
The connection with other duties
Assessing mental stress does not stand alone. It feeds into several other duties, and using that saves effort.
The results belong in safety training: if availability rules have been decided, employees have to know them. They belong on the agenda of the occupational safety committee, because that is where the effectiveness of measures is tracked. And they touch on working time, because blurred boundaries and breaches of the rest period are among the most common findings.
Conversely, other sources give indications without a separate survey: notable turnover in one area, clusters of short absences, recurring themes in exit conversations. These signals do not replace the assessment, but they show where to look more closely.
How to tell the section is complete
An inspection does not ask about the method but about the result. These five points should be traceable in your documentation:
- All five factor areas were considered, not just one.
- There are concrete findings, not a general statement such as "strain within the usual range".
- Each finding has a measure with an owner and a deadline.
- The effectiveness review is documented, not only the measure.
- The evaluation is aggregated so that no conclusions about individuals are possible.
Safety Club includes mental stress in the risk assessment for office and administrative businesses from the outset: structured, evaluated anonymously and documented ready for inspection, supported by an occupational safety specialist on site. Let us show you what this looks like in an office.
