Reasonable Adjustments Mental Health at Work

Work can become hard to manage long before someone reaches crisis point. Mental health problems can affect sleep, concentration, confidence and the ability to keep up with a fixed routine.

Looking for mental health adjustments often starts when usual ways of coping stop working. Mental health support may include workplace changes and confidential help through an employee assistance programme. The right approach can reduce pressure without lowering someone's dignity or treating them as a problem to manage. It can also help employers keep skilled people in work.

Key Takeaways

• Mental health conditions can be disabilities under the Equality Act 2010 when they have a substantial, long-term effect on normal day-to-day activities. Recurring conditions can qualify even when symptoms come and go.

• Requests should explain the disadvantage at work rather than focus only on a diagnosis. Employees do not usually need to share every medical detail, but relevant evidence may help an employer assess what is reasonable.

• Reasonable adjustments may include flexible hours, a phased return, written priorities, quieter workspaces, fewer last-minute changes and scheduled communication. The right adjustment should address the source of strain while supporting the role’s essential requirements.

• Employers should listen respectfully, consider adjustments promptly, use stress risk assessments or occupational health appropriately, and agree clear review dates. If an adjustment is refused, ask for the reasons in writing and consider alternative options or further advice.

The Legal Starting Point for Mental Health Adjustments

Under the Equality Act 2010, disability is one of the protected characteristics. The protection can cover employees, workers and job applicants. It can also apply to non-visible disabilities where a mental health condition meets the statutory test.

The Equality Act test is about impact

A diagnosis alone does not decide the question. The condition must have a substantial effect on normal day-to-day activities, meaning more than minor or trivial. It must also be a long-term condition, usually lasting, or likely to last, 12 months or more. At work, those effects may create a substantial disadvantage compared with people without the disability.

Difficulties with concentrating, following instructions, interacting with people, keeping to set times or coping with ordinary tasks can all be relevant. The Government's disability definition sets out this test in plain terms.

Anxiety, depression, obsessive compulsive disorder, bipolar disorder, PTSD and eating disorders can meet the definition. However, the protected characteristics framework does not rely on assumptions about a person’s diagnosis. Each situation depends on how the condition affects them.

Recurring conditions can still qualify

Symptoms often come and go. A few better weeks do not cancel out a recurring condition. The overall pattern matters, including whether symptoms are likely to return.

Once an employer knows, or could reasonably be expected to know, about disability-related disadvantage, its legal duty is to consider reasonable adjustments that reduce it. Acas guidance on mental health and the law explains this duty alongside protection from disability discrimination.

Start with the disadvantage, not the diagnosis

A request for reasonable adjustments should focus on the mismatch between the person and the way work is organised. It should explain any substantial disadvantage this creates. For example, a sudden increase in customer calls may trigger panic. An open-plan office may also make concentration impossible during a depressive episode because of the physical working environment.

Clear guidance on mental health adjustments helps both sides move beyond vague statements such as "I'm struggling". It turns a difficult experience into a practical discussion about what needs to change.

When the disadvantage is difficult to define, a stress risk assessment may identify patterns in workload, communication or the environment.

You can ask without sharing every detail

Employees don't have a general duty to reveal a particular medical diagnosis when requesting support. People with non-visible disabilities can usually explain the impact instead, including when applying for a role: "My concentration drops when priorities change several times a day", or "I am finding early starts difficult because of medication and disrupted sleep."

An employer may need information before deciding what is reasonable, but requests should be relevant and proportionate. That could include a fit note, a conversation with occupational health, or medical evidence you agree to provide. An employee assistance programme may offer a confidential support route, but it isn't a substitute for workplace changes. Acas advice on mental health adjustments gives examples of how these conversations can work.

The adjustment should fit the role

An employer doesn't have to accept the first idea suggested. However, "we do not normally do that" isn't a proper assessment. They should consider whether a change would work, how practical it is, what it costs, and whether another option could achieve the same result.

Job applicants can request reasonable adjustments too. A quieter interview space or extra time for a written task may remove an unnecessary barrier. Clear directions or questions sent in advance can help too. This can be especially important where disability is among the relevant protected characteristics.

Practical reasonable adjustments for mental health

Workplace changes are often modest. The best reasonable adjustments address the source of strain while supporting a reasonable workload and the role’s essential requirements, rather than asking someone to cope harder with unclear expectations.

Changes to hours and working patterns

Flexible working hours can help with insomnia, medication side effects or rush-hour anxiety. Hybrid working may help where the role allows it. Predictable office days and clear working arrangements can support people who struggle with isolation at home.

A phased return after sickness absence can prevent someone being dropped straight back into full hours and a reasonable workload. A return to work plan can set out staged hours, duties and review points. The Government's examples of workplace adjustments include flexible or part-time hours during a return to work.

Changes to tasks, communication and space

Some changes affect how work happens rather than how much work is done. Written priorities, a weekly check-in, meeting agendas in advance and fewer last-minute changes can lower stress without reducing standards. A stress risk assessment can help identify whether demands, control or the environment are creating avoidable pressure.

Barrier at work	Possible adjustment	How it may help
Competing deadlines cause overwhelm	Agree priorities, stage deadlines, or reallocate a temporary task	The employee can focus on the work that matters most
Hot-desking makes the physical working environment harder to manage	Provide a regular desk or a quieter workspace	The setting becomes more predictable and less draining
Unplanned calls trigger panic	Use written communication where possible and schedule calls	The employee has time to prepare
Returning after absence feels unmanageable	Use a phased return and review absence triggers	Work builds up at a safer pace
Vague instructions increase anxiety	Set out goals, deadlines and check-in points in writing	Expectations become clearer

A change may be temporary, permanent or tested for a few weeks. Regular reviews matter because a helpful change in January may not suit a different workload in June.

How to ask for adjustments at work

Writing a request for reasonable adjustments can feel exposing, especially if you worry about being judged. Preparation gives you something concrete to return to if nerves take over in the meeting.

Prepare a short picture of the problem

Before speaking to your line manager or human resources team, write down the parts of work that affect you most. Keep your notes factual and linked to your job responsibilities.

• Record when the difficulty occurs, such as after back-to-back meetings or during overnight deadline changes.

• Describe the impact on your work, sleep, concentration, attendance or confidence.

• Suggest one or two changes that could reduce the problem.

• If workload or wider pressure is part of the difficulty, ask whether a stress risk assessment could help identify practical changes.

• Consider what evidence you can share, if any, and what information you want kept private.

You do not need a perfect solution. You can request a trial period and agree a review date to see whether the changes help.

  "I want to keep doing my job well. Recently, the pace and changing priorities have affected my concentration and sleep. Could we discuss temporary adjustments, such as written priorities and a weekly workload review, then review how they are working in four weeks?"  

Keep the meeting focused and recorded

Ask for a private meeting rather than raising the issue in a busy corridor. You can also ask whether you may bring a trade union representative, colleague or another support person.

Afterwards, send a short email confirming what was discussed, what will happen next and when you will review it. This avoids misunderstandings and gives both sides a clear record.

What a line manager and HR should do

A supportive response is practical, respectful and timely, helping employers meet their legal duty to consider reasonable adjustments. Managers don't need to become therapists or ask someone to prove their distress. Their job is to listen, identify barriers and seek proportionate advice when needed.

Respond to stress with curiosity and care

A manager can ask which parts of work feel hardest, what has changed and what would make the next few weeks more manageable. Attendance, mood and appearance don't reliably show how difficult mental health problems may be. Managers should avoid assumptions about non-visible disabilities.

Confidentiality also needs care. Tell human resources, payroll or a team lead only what they need to put an adjustment in place.

A wellbeing webinar, mental health support or an employee assistance programme can be useful. Yet these supports can't resolve bullying, unclear roles or an unmanageable workload. Employers need to address the work conditions causing harm and provide a reasonable workload.

Use a stress risk assessment and occupational health well

A stress risk assessment can identify pressures around demands, control, working relationships, role clarity, support and organisational change. It can show where work-related stress is arising and what action is needed. Organisations with five or more employees must record their risk assessment findings in writing.

For an individual plan, name the risk, agree the action, assign responsibility and set a review date. Occupational health can provide an independent view of how a condition affects work and which reasonable adjustments may help. The Acas occupational health guide explains how employers can use this service appropriately.

This advice informs the decision; it does not transfer responsibility.

Review changes and deal with refusals early

Mental health is not always predictable. Someone may need more support during a relapse, after a medication change, or during a phased return from sickness absence. A good plan sets out how the employee will raise a problem early, when the arrangement will be reviewed, and how it fits within a return to work plan.

When an adjustment needs changing

If reasonable adjustments aren't helping, return to the original disadvantage. Perhaps flexible hours were useful, but the overall demands still don't provide a reasonable workload. Perhaps remote work reduced anxiety, but isolation has increased. A stress risk assessment may help identify the underlying pressures. The answer may be a different change, rather than ending support altogether.

Keep a record of requests, meetings, trial periods, decisions and their effects. This is useful for the employee, manager and HR team.

If the employer says no

Ask for the reasons in writing and request alternative options. You can then check the workplace policy, speak to a union representative, or raise a formal grievance if informal discussion doesn't resolve the issue.

Get advice promptly about work-related stress if you believe an employer has failed to make an adjustment or treated you unfairly because of disability or other protected characteristics. Employment tribunal time limits can be short. The Acas guidance is a sensible starting point before deciding what to do next.

Frequently Asked Questions

Do I need a diagnosis to request reasonable adjustments for mental health?

No. You can usually explain how a mental health condition affects your work without sharing every detail of a diagnosis, although an employer may need relevant information to assess the request.

What reasonable adjustments can help with mental health at work?

Possible adjustments include flexible or predictable hours, a phased return, written instructions, regular check-ins, fewer last-minute changes and a quieter workspace. The adjustment should address the specific disadvantage and remain workable for the role.

Can I request reasonable adjustments if my symptoms come and go?

Yes. A recurring mental health condition may still meet the Equality Act 2010 definition of disability if its overall effects are substantial and long-term. Better periods do not necessarily cancel out the condition or the need for support.

What should I do if my employer refuses an adjustment?

Ask for the reasons in writing and discuss alternative options, such as a trial adjustment or a stress risk assessment. You can also speak to a trade union representative, raise a formal grievance or seek prompt advice about your rights.

A More Workable Way Forward

Effective reasonable adjustments change the part of work that creates disadvantage. A clearer workload, a quieter desk, protected therapy appointments or a gradual return can make work feel manageable again.

The strongest plans come from honest discussion, clear written actions and regular reviews. They recognise that people can need support without losing their value, capability or privacy.
