These FAQs answer key questions about workplace mental health, covering how wellbeing affects employees and the organisation, legal obligations, and how employers can support their workforce.
Mental health and wellbeing is important in the workplace because good mental health supports employees’ performance, loyalty and long-term retention, whereas poor mental health often leads to absence, reduced productivity and increased staff turnover.
Evidence shows that workplace stress, depression or anxiety alone contributed to 17.1 million working days lost in one year, highlighting the scale of the problem when wellbeing is neglected.
Supportive work environments that promote mental wellbeing lead to improved employee satisfaction, stronger engagement, higher productivity and lower rates of absenteeism and presenteeism.
Poor mental health doesn’t just affect the individual employee. When someone is struggling, it can increase team workload, reduce collaboration, and affect morale, as colleagues may take on extra tasks, experience uncertainty, or feel stressed by ongoing disruption. Research shows that poor mental health contributes to reduced productivity and presenteeism across teams, not just for the person directly affected.
The World Health Organisation highlights that poor working conditions and unmanaged mental health issues can disrupt communication, reduce trust, and increase conflict within teams, all of which weaken organisational performance.
Mental health awareness is important in the workplace because it helps employees and managers recognise early signs of stress, anxiety, or other mental health issues, allowing support to be offered before problems escalate.
Raising awareness reduces stigma, encourages open conversations, and promotes a culture where people feel safe seeking help.
You can promote mental health in the workplace by creating a supportive culture, training managers to recognise and respond to issues, encouraging open communication, offering flexible working where possible, providing access to wellbeing resources or employee assistance programmes, managing workloads fairly, and regularly reviewing risks that may contribute to stress.
A mental health champion is an employee who promotes positive mental wellbeing, raises awareness of mental health issues, and helps create a supportive culture.
Mental health champions are not clinicians, but trained individuals who signpost colleagues to appropriate support, encourage open conversations, challenge stigma, and promote wellbeing initiatives. Their role helps organisations spot issues early, support staff more effectively, and strengthen overall workplace mental health.
An employer’s obligation to an employee with mental illness is to take reasonable steps to protect their health, ensure they are not placed at unnecessary risk, and support them to work safely and effectively.
Employers must comply with the Health and Safety at Work etc. Act 1974, which requires them to assess and manage workplace risks (including stress and mental health risks) as part of their general duty of care. They must also follow the Management of Health and Safety at Work Regulations 1999, which require suitable and sufficient risk assessments and appropriate control measures.
If the mental illness meets the definition of a disability under the Equality Act 2010, employers have a legal duty to make reasonable adjustments. These may include modified duties, flexible working, altered hours, additional support, or changes to workload or supervision. Employers must ensure that employees are not discriminated against because of their condition.
A stress risk assessment is the process of identifying, assessing, and controlling work-related stress risks in the workplace.
It focuses on how work is organised and managed, rather than on individuals’ medical conditions. In the UK, this approach is based on the Health and Safety Executive (HSE) Management Standards for work-related stress, which look at six key areas:
Employers are expected to identify stress-related hazards in these areas, decide who might be harmed, put controls in place to reduce the risk, and review the assessment regularly.
Five common signs of work-related stress are:
The 3-3-3 rule in mental health is a simple grounding technique used to help reduce anxiety and regain focus. It involves identifying three things you can see, three things you can hear, and three parts of your body you can move (or three physical sensations you can notice). This quick exercise helps interrupt spiralling thoughts and bring attention back to the present moment.
A manager should start a mental health conversation in a supportive, non-judgemental, and practical way, focusing on work and wellbeing rather than diagnosis.
A good approach is to:
Managers should focus on how work may be affecting the person, what support might help, and what adjustments could be made. Tools like a Wellness Action Plan can help structure the conversation by identifying what helps the person stay well, early warning signs, and agreed support steps.
The goal is not to diagnose or counsel, but to open a safe conversation, show support, and agree next steps where needed.
No. You are not legally required to tell your employer that you have a mental health condition.
Mental health information is private medical data, and it is your choice whether to disclose it. However, there are a few important points to consider:
Choosing to share information about how your health affects your work can help your employer provide appropriate support and adjustments.
Your occupational health report is shared on a need-to-know basis only. It is normally seen by HR and the relevant manager responsible for supporting you at work, and sometimes by health and safety or senior management if adjustments or risk controls are required.
The report focuses on functional information, such as whether you are fit for work, what adjustments may be helpful, and any recommended review timescales.
A phased return is a temporary, planned arrangement that helps someone return to work gradually after a period of absence, including absence related to mental health.
For mental health, a phased return often focuses on reducing pressure while confidence and resilience rebuild, rather than physical recovery. It may include shorter working hours, fewer days at work, adjusted duties, reduced workload, or avoiding particularly stressful tasks or environments for a period of time.
The arrangement is usually agreed between the employee, manager, HR, and sometimes occupational health. It is reviewed regularly and adjusted as the employee’s health improves, with the aim of returning to normal duties over an agreed timeframe.
A Wellness Action Plan (WAP) is a practical, personalised document created jointly by an employee and their manager to support mental health and wellbeing at work.
It sets out what helps the individual stay well at work, what can trigger stress or difficulty, the early warning signs that they may be struggling, and the actions or adjustments that can help prevent things from escalating. The plan also states how and when support should be reviewed.
A WAP is not a medical record or performance tool. It’s a living, supportive agreement that helps managers respond early, have constructive conversations about wellbeing, and put the right support in place.
You can be dismissed while off sick with stress, but only in limited circumstances and your employer must follow a fair, lawful process.
An employer may consider dismissal if you are unable to return to work for a long period or cannot perform your role, but only after they have:
Dismissing someone without taking these steps or treating them unfavourably because of a mental health condition that meets the definition of a disability, may amount to unfair dismissal or disability discrimination.
You can be dismissed while off sick with depression in the UK, but only in limited circumstances and only if your employer follows a fair, lawful process.
Depression is likely to be considered a disability under the Equality Act 2010 if it has a substantial, long-term impact on your daily life. In that case, your employer must make reasonable adjustments and cannot dismiss you for a reason related to your condition without first exploring adjustments, medical evidence, alternative roles, and support options.
Dismissal is only lawful if:
You cannot be fairly dismissed simply for being off sick with depression. The employer must show that continued absence or inability to perform essential duties makes the job unsustainable and that all legal obligations have been met.
Yes, you can take legal action against your employer for stress and anxiety in the UK, but only in specific circumstances.
You may be able to bring a personal injury claim if you can show that your employer failed in their duty of care, the work situation caused you foreseeable harm, and you suffered a recognised psychiatric injury (such as clinical anxiety or depression) as a result.
You might also have grounds for a constructive dismissal claim if the employer’s actions or inaction created an intolerable working environment that forced you to resign.
If the stress or anxiety relates to a protected characteristic, or if the behaviour amounts to harassment under the Equality Act 2010, you could bring an Employment Tribunal claim for discrimination.
In all cases, success depends on clear evidence, medical diagnosis, and demonstrating that the employer failed to take reasonable steps once aware of the risk.
