Emma had always prided herself on her resilience. But after six months of relentless deadlines, understaffing, and a manager who dismissed her concerns, she found herself staring at her laptop screen, unable to type. Her heart was racing, her mind was blank, and the thought of opening her emails triggered a wave of nausea.

This is not a story of weakness. It is a story of stress.

Work-related stress, depression and anxiety now account for 52 percent of all work-related ill health cases in Great Britain, and the Health and Safety Executive recorded 22.1 million working days lost to it in 2024 to 2025, more than to any other cause including musculoskeletal injury.

Yet despite those numbers, most UK employees have never been told what they are actually entitled to. Many do not know they can be signed off with stress, how to request time off for it, or what happens to their pay while they are away, especially now that the rules on sick pay have changed.

This guide covers what you need to know about stress leave in the UK: your legal rights, how to request it, what happens to your pay under the reformed Statutory Sick Pay system, and what you are allowed to do while signed off.

What Is Stress Leave?

Stress leave is a period of sickness absence taken when an employee is too unwell to work because of a mental health condition such as anxiety, depression or burnout.

It is not a separate legal category. In UK law it is ordinary sick leave, taken for a mental health reason rather than a physical one, and it is treated the same way for pay, process and protection. If you cannot work because of stress, anxiety or depression, you are entitled to take sick leave and, where you meet the criteria, to be paid Statutory Sick Pay.

Key Statistics on Stress and Mental Health at Work

Your Legal Rights to Stress Leave

The Legal Framework

UK employment law treats mental health conditions as legitimate reasons for sickness absence. The key protections are:

The Equality Act 2010. Where stress has developed into a diagnosed condition such as anxiety or depression that has a substantial and long-term adverse effect on daily activities, it can be classed as a disability. That brings protection from discrimination and a duty on your employer to consider reasonable adjustments.

The Health and Safety at Work etc Act 1974. Employers have a legal duty to ensure, so far as reasonably practicable, the health, safety and welfare of employees, and that duty covers mental health, not only physical safety.

The Management of Health and Safety at Work Regulations 1999. Employers must carry out risk assessments that consider stress, not just physical hazards. Failing to do so can lead to enforcement action from the HSE.

The Employment Rights Act 1996. Employees have the right to take sick leave when unfit for work, and mental health conditions are included on exactly the same basis as physical ones.

The Working Time Regulations 1998. Excessive hours are a recognised contributor to stress. Workers cannot be required to work more than an average of 48 hours a week unless they have signed an opt-out agreement, and even then the daily and weekly rest entitlements still apply. Our guide to UK overtime laws covers where those limits sit.

Can an Employer Refuse Stress Leave?

No, not if you are genuinely unwell and you follow the correct procedure.

You have the same right to sick leave for stress as you would for a physical illness, and your employer cannot refuse a genuine request for sickness absence because the cause is mental rather than physical. What your employer can do is ask for evidence, such as a fit note once your absence passes seven days, and decide whether to pay more than the statutory minimum through a contractual sick pay scheme.

How to Get Signed Off with Stress

Getting signed off with stress starts with recognising the warning signs and making an appointment with your GP to discuss your symptoms and what is triggering them at work. Your GP will assess your condition and, if appropriate, issue a fit note, which you then submit to your employer following its sickness reporting procedure.

Step 1: Recognise the Warning Signs

Before you can request stress leave, you need to recognise that you need it. Common signs that work-related stress is affecting your health include:

• Persistent exhaustion and sleep problems
• Increased anxiety, irritability or mood swings
• Difficulty concentrating or making decisions
• Physical symptoms such as headaches, stomach problems or heart palpitations
• Withdrawing from social situations
• Loss of interest in things you normally enjoy
• Increased reliance on alcohol or caffeine

Step 2: Speak to Your GP

The most common route to stress leave is through your GP. They will assess your symptoms, discuss your work situation, and decide whether you are unfit to work.

What to tell your GP:

• How your work is affecting your mental health
• Your specific symptoms, such as anxiety, insomnia or panic attacks
• How long you have been experiencing these symptoms
• Any triggers at work, including workload, management issues or bullying
• Any coping strategies you have already tried

Your GP may suggest a period of rest, a phased return to work, adjustments to your hours, or a referral for counselling or therapy.

Step 3: Obtain a Fit Note

You do not need a fit note for the first seven calendar days of absence, including weekends. You can self-certify using your employer’s own form or the standard SC2 form, and your employer cannot demand a fit note during this window.

Beyond seven days, you need a fit note from your GP. It will say either that you are not fit for work, meaning a full sickness absence, or that you may be fit for work with recommended adjustments. A work-related stress fit note is not a distinct category. It works exactly the same as a fit note for a physical condition, stating that you are unable to work and for how long.

Step 4: Notify Your Employer

Once you have your fit note, or before day seven if you are self-certifying, notify your employer as soon as possible and follow the sickness reporting procedure set out in your contract or staff handbook.

Key points to remember:

• Follow your employer’s sickness reporting procedure
• Provide your fit note, or self-certification, promptly
• Keep in contact with your employer as agreed
• Be honest about your condition, but you do not need to share your full medical history

Step 5: Plan Your Recovery and Return

While you are off work, focus on your recovery. This may include rest, therapy, medication, exercise and addressing the underlying causes of your stress. When you feel ready, discuss a return-to-work plan with your GP and employer. This may involve a phased return, adjusted duties or reduced hours to make the transition sustainable.

How Long Can You Be Signed Off with Stress?

There is no legal maximum. The duration depends entirely on your individual circumstances and your GP’s clinical judgment.

Typical durations:

• Short-term stress leave: often one to four weeks for acute stress or burnout
• Medium-term stress leave: one to three months for more severe anxiety or depression
• Long-term stress leave: three to twelve months or more for serious mental health conditions

According to the HSE, workers affected by stress, depression or anxiety take an average of 22.9 working days off, close to a month.

Your employer cannot force you back to work before you are ready. They can ask for updates on your condition and may arrange an occupational health assessment to understand your situation and a realistic return date, but the decision on fitness to work sits with medical judgment, not with management.

What Are You Allowed to Do When Off Sick with Stress?

This is one of the most common worries for anyone signed off with stress. The short answer is that you are not confined to your home, and you can do things that support your recovery and wellbeing.

Going out for fresh air or to see supportive people is part of recovery, not a breach of your sick leave. What matters is consistency: your activities should support getting better, not contradict the reason you are off. Taking on a physically demanding second job or a strenuous holiday while signed off with stress is likely to raise questions, because if you are well enough for that, your employer may reasonably ask why you are not well enough for your own role.

Do You Get Paid for Stress Leave in the UK?

It depends on your employment contract, but most employees are covered by Statutory Sick Pay at minimum, and the rules changed significantly from 6 April 2026.

Statutory Sick Pay After the 2026 Reform

Under the Employment Rights Act 2025, Statutory Sick Pay is now payable from the first day of sickness absence. The old rule, where the first three days were unpaid waiting days, has been removed.

The lower earnings limit has also been abolished. Previously, anyone earning under the threshold, around 125 pounds a week, was excluded from SSP altogether. Now, entitlement is calculated as 80 percent of your average weekly earnings, capped at the statutory maximum rate. From 6 April 2026 that maximum is 123.25 pounds a week. In practice this means lower-paid workers, including many part-time and zero-hours staff, are now covered for the first time rather than receiving nothing.

Two things have not changed. SSP can still be paid for up to 28 weeks for one period of sickness, including linked periods of absence, and you still do not need a fit note for the first seven calendar days. Self-certification is enough for that initial window, and your employer cannot demand medical evidence before day eight.

Contractual Sick Pay

Many employers offer occupational sick pay, also called contractual sick pay, that is more generous than the statutory minimum. This may include full pay for a set number of weeks, half pay for a further period, or company sick pay topped up to full salary. Your contract or staff handbook should set out exactly what you are entitled to, and it is worth checking this before you assume SSP is all you will receive.

Average Time Off Work for Depression and Stress

Average time off varies significantly with severity, treatment and individual circumstances.

Where a diagnosed mental health condition has a substantial and long-term effect on daily life, it can be classed as a disability under the Equality Act 2010, bringing additional protections including the right to reasonable adjustments.

Can You Be Dismissed or Made Redundant While Off Sick with Stress?

Being on stress leave does not make you immune from dismissal, and this catches a lot of employees off guard.

An employer can still dismiss someone on stress leave, but only through a fair process. That generally means following a proper capability procedure, obtaining up to date medical evidence, exploring reasonable adjustments, and considering whether the condition amounts to a disability under the Equality Act 2010 before any decision is made.

Dismissing someone simply because they are off sick, without that process, is likely to be unfair and, where a disability is involved, potentially discriminatory.

Redundancy works similarly. You can be made redundant while on stress leave if the redundancy is genuine and would have happened regardless of your absence, and if the selection process is fair and not influenced by the sickness itself. What an employer cannot do is use a sickness absence as cover to remove someone it would rather not manage through a proper process.

Serious misconduct unconnected to the illness, such as gross misconduct discovered during the absence, can also still be addressed. The common thread across all three situations is process: the more serious the action, the more clearly it needs to be justified on grounds that have nothing to do with the fact that you are unwell.

The HSE Management Standards: How Employers Should Assess Stress Risk

When employers talk about a stress risk assessment, they are usually referring to the HSE Management Standards, the recognised UK framework for identifying and managing the causes of work-related stress. It groups risk into six areas.

• Demands. Workload, work patterns and the physical environment
• Control. How much say someone has over how they do their job
• Support. The encouragement and resources provided by the organisation, managers and colleagues
• Relationships. Promoting positive working and dealing with conflict or unacceptable behaviour
• Role. Whether people understand their role and are not given conflicting responsibilities
• Change. How organisational change, large or small, is managed and communicated

HSE provides a free Stress Indicator Tool that lets employers survey staff against these six areas and identify where the real pressure points sit, rather than guessing. If work is a genuine part of what is causing your stress, this is the framework your employer should be using to investigate it, and it is worth naming when you raise a concern, since it shows you understand the standard your employer is actually being held to.

What Are an Employer’s Responsibilities?

Employers have both legal and practical duties to support employees experiencing work-related stress.

Legal Duties

• Carry out stress risk assessments that identify workplace factors contributing to stress, ideally using the HSE Management Standards above
• Make reasonable adjustments for employees with a diagnosed mental health condition
• Maintain sensitive, appropriate contact during sickness absence
• Support a return to work through phased returns, adjusted duties or amended hours
• Pay Statutory Sick Pay, or contractual sick pay where it applies
• Follow a fair process when managing long-term sickness absence

Best Practice

What Happens If Work Is Causing My Stress?

You have options, and your employer has obligations.

Step 1: Raise the Issue Informally

If you feel able to, speak to your line manager or HR about your concerns. Be specific about the cause, whether that is workload, deadlines, lack of support, bullying, or the working environment. A vague complaint is hard to act on. A specific one is not.

Step 2: Make a Formal Grievance

If an informal conversation does not resolve things, you can raise a formal grievance under your employer’s grievance procedure.

Step 3: Consider a Flexible Working Request

If a change to your working pattern, such as reduced hours, hybrid working or compressed hours, could reduce the pressure, you have the right to make a flexible working request.

Step 4: Seek Medical Advice

Visit your GP to discuss your symptoms and get medical evidence of how work is affecting you.

Step 5: Escalate if Nothing Changes

If your employer will not address work-related stress, you can report the matter to the Health and Safety Executive, contact ACAS for free advice, or consider an employment tribunal claim where you have been treated unfairly. Keeping a written record of what you raised and when, alongside your fit notes, is what makes any of these routes actually workable later.

How Smart Workforce Supports Employee Wellbeing

Managing stress leave, tracking attendance and planning a return to work is genuinely difficult to do consistently by hand, especially across shift-based teams. Smart Workforce gives UK employers a single place to:

• Track sickness absence and spot stress-related patterns before they become long-term absence
• Schedule and document return-to-work meetings
• Maintain a clear record of contact with employees on sick leave
• Manage the wider policies and documentation that an effective HR policy needs to hold up to scrutiny

For employees, a workplace with clear policies, supportive management and consistent absence management is one where stress is more likely to be addressed before it escalates into long-term leave. Our guide to effective absence management covers what that looks like in practice, and if stress sits alongside other types of leave your team needs to track, our guide on managing different types of leave is a useful next read.

Conclusion

Stress leave in the UK is not a separate legal entitlement. It is sick leave taken for a mental health reason, and it carries exactly the same rights as sick leave taken for a physical illness.

Your rights, in summary:

• You can take sick leave for stress, anxiety or depression
• You are entitled to Statutory Sick Pay from day one of your absence, at 80 percent of your average weekly earnings up to 123.25 pounds a week
• Your employer cannot refuse a genuine request for stress leave where you have followed the proper procedure
• You can do things that support your recovery while you are off sick
• You are protected from discrimination under the Equality Act 2010 where your condition amounts to a disability
• You can still be dismissed or made redundant while off sick, but only through a fair and properly evidenced process

If you take one thing from this guide, make it this: know the difference between what your employer must do and what it is choosing to do. The statutory minimum is a floor, not a ceiling, and your contract may give you considerably more. Read it before you assume you know where you stand.
