A manager may ask whether an employee is “fit to return” after anxiety, depression or work-related stress. That question is too narrow to answer safely. An occupational health mental health assessment is not a test of diagnosis, resilience or loyalty. It is a structured clinical assessment of how health affects work, how work may affect health, and what practical steps can support safe, sustainable work participation.
For Occupational Health practitioners, the quality of the assessment lies in translating often complex clinical information into proportionate, functional and defensible workplace advice. That means listening carefully, preserving confidentiality and avoiding recommendations that drift into management decisions.
A good assessment establishes the employee’s current health position, functional capacity, relevant risks and likely workplace needs. It should help the employee, employer and treating clinicians understand what is possible now, what may need to change temporarily, and what requires review.
Diagnosis matters, but it is rarely the whole answer. Two employees with the same diagnosis may have very different functional limitations depending on symptom severity, treatment effects, job demands, working environment, support networks and the relationship between their work and their health.
The key Occupational Health question is therefore not simply, “Does this person have a mental health condition?” It is, “How does their current state affect their ability to undertake the essential demands of this particular role?”
This distinction is especially important for safety-critical work, lone working, driving, clinical duties, work at height, access to vulnerable people and roles involving significant responsibility for others. A restriction may be necessary, but it should be based on evidence and reviewed rather than imposed indefinitely.
Before the consultation, clarify the referral question and obtain a meaningful job description where possible. Generic descriptions are often insufficient. A role called “supervisor” could involve office-based planning, operating machinery, responding to emergencies, managing conflict, rotating shifts or all of these.
Explore the essential tasks, working hours, performance pressures, interpersonal demands and safety implications. Ask about the employee’s usual work pattern and what has changed. An individual who can manage focused work for several hours at home may still struggle with a noisy open-plan environment, night shifts, customer confrontation or a high-volume clinical workload.
This approach avoids an unhelpful binary outcome of fit or unfit. Many cases sit in the middle: fit for some duties, fit with adjustments, or temporarily unfit pending treatment and review. The recommendation should reflect that reality.
A consistent framework makes difficult consultations easier to manage and supports clear report writing. Begin by explaining your role, the purpose of the assessment, the limits of confidentiality and how consent will be handled. Employees should understand that the employer receives occupational advice, not a detailed account of their private history unless they explicitly agree to its disclosure.
Take a focused history of the presenting problem. Establish symptom onset, progression, previous episodes, current treatment, medication effects, therapeutic support and relevant physical health factors. Explore sleep, concentration, energy, motivation, irritability, panic symptoms, trauma-related symptoms and substance use where clinically relevant.
Then move carefully to function. Ask what a typical working day currently looks like and identify the point at which symptoms interfere. Can the employee plan tasks, sustain attention, make decisions, manage deadlines, communicate with colleagues and respond to unexpected demands? Are they attending work but struggling to function effectively, or absent because the demands are currently beyond capacity?
The relationship between work and health deserves specific attention. Work may be a positive source of structure, purpose and social connection. It may also be contributing to deterioration through workload, bullying, unresolved conflict, traumatic exposure, lack of control or inadequate support. Avoid assuming causation from timing alone. Instead, document the employee’s account, consider other contributing factors and identify matters that may require organisational attention.
Risk assessment should be proportionate, direct and sensitively undertaken. Ask about thoughts of self-harm or suicide, intent, plans, access to means, previous attempts and protective factors. Consider risk to others where this is clinically indicated, including severe agitation, psychosis, impaired judgement or occupational situations where symptoms could create a safety concern.
A positive response does not automatically mean emergency action, and a negative response does not remove all concern. Use clinical judgement, assess immediacy and ensure the employee knows how to access appropriate support. If there is immediate and serious risk, follow local safeguarding and emergency procedures. Record your reasoning and actions clearly.
Occupational Health clinicians must also distinguish personal clinical risk from workplace risk. An employee may be safe to remain at work with support, while temporarily unsuitable for a specific activity such as driving for work, working alone at night or undertaking high-consequence decision-making. These are different questions and should be addressed separately.
Recommendations should be specific enough to be useful but flexible enough for the employer to implement reasonably. “Reduce stress” is not an adjustment. Neither is “avoid difficult colleagues” where the problem is unresolved workplace conflict.
Instead, connect each recommendation to the relevant functional difficulty and workplace demand. For example, an employee recovering from severe insomnia and impaired concentration may benefit from a temporary reduction in hours, predictable daytime shifts, protected breaks and a phased increase in workload. Someone experiencing panic in crowded settings may need a quieter workspace, gradual reintroduction to customer-facing duties or temporary access to remote work where the role permits.
The adjustment is not always less work. For some people, clarity of priorities, regular management check-ins, reduced exposure to a particular trigger, additional supervision or time to attend treatment may be more helpful than a blanket reduction in duties. It depends on the role, the employee’s symptoms and the resources available.
Be realistic about feasibility. Occupational Health can advise on medical suitability and potential adjustments, but the employer decides how work is organised. A defensible report explains the health rationale, identifies the expected duration and recommends review. It does not guarantee that an adjustment can be delivered or direct managers to adopt a particular staffing model.
Mental health conditions may meet the definition of disability under the Equality Act 2010 where they have a substantial and long-term adverse effect on normal day-to-day activities. Occupational Health should avoid making definitive legal findings, but can offer clinically informed advice on whether the available evidence suggests the employer should consider its duty to explore reasonable adjustments.
Long-term does not mean permanent. Symptoms that have lasted, or are likely to last, 12 months can be relevant. A fluctuating condition may also have substantial effects at certain times. Your report should describe functional impact rather than relying only on diagnostic labels.
Consent remains central. Obtain informed consent before releasing the report, and share only what is necessary to answer the referral. A manager may want details of therapy, medication or relationship difficulties; that does not mean those details belong in the report. Clear boundaries protect the employee and strengthen trust in Occupational Health.
A useful report answers the referral questions in plain language. State whether the employee is fit, fit with adjustments, temporarily unfit or whether further information is needed. Explain the functional basis for that opinion without unnecessary clinical detail.
Set out any recommended restrictions or adjustments, their anticipated timescale and a sensible review point. If there are safety-critical concerns, specify the activity affected and the reason for the restriction. Avoid vague statements such as “may struggle” unless uncertainty is unavoidable and explained.
It is equally important to identify what is outside Occupational Health’s remit. You may note that the employee reports workplace concerns and recommend that these are addressed through the appropriate internal process, but you are not there to investigate grievances or determine whether management acted fairly.
Mental health referrals can feel difficult because they require clinical reasoning, legal awareness, communication skill and a practical understanding of work. Confidence grows when practitioners repeatedly practise the same translation: symptoms to function, function to job demands, and job demands to proportionate advice.
For clinicians developing this skill, case-based learning is particularly valuable. Working through scenarios involving absence, presenteeism, safety-critical duties, return to work and reasonable adjustments makes the assessment process more structured and easier to apply under pressure. Zosh Occupational Health Academy uses this practical workplace focus to help learners move from theory to clearer fitness-for-work decisions.
The most helpful report is rarely the longest one. It is the one that gives an employee a fair assessment, gives an employer usable boundaries, and gives everyone a realistic route back towards safe and meaningful work.
