⚖ Know Your Rights at a Glance
- Mental health can be a disability: If your condition has a substantial and long-term (12 months+) adverse effect on daily activities, the Equality Act 2010 applies.
- Reasonable adjustments: If your mental health condition is a disability, your employer must make reasonable adjustments to remove disadvantages you face.
- SSP from day one: If you're signed off sick with a mental health condition, SSP applies from day one of absence (from 6 April 2026).
- Stress as a workplace injury: Chronic workplace stress caused by employer negligence can give rise to a personal injury claim.
- Dismissal: Dismissing someone because of a mental health condition that amounts to a disability is automatically unlawful under the Equality Act.
- Confidentiality: You don't have to disclose your mental health condition to your employer — but disclosure may help you access adjustments.
When does mental health become a legal disability?
Under the Equality Act 2010, a person has a disability if they have a physical or mental impairment that has a substantial and long-term adverse effect on their ability to carry out normal day-to-day activities.
Long-term means 12 months or more, or likely to last 12 months. Substantial means more than minor or trivial. Many mental health conditions qualify — depression, anxiety disorders, PTSD, bipolar disorder, OCD, schizophrenia, and others. A diagnosis is not required — the test is functional.
If your condition qualifies, your employer must make reasonable adjustments and must not discriminate against you.
Reasonable adjustments for mental health
Reasonable adjustments can include:
- Flexible start/finish times or working from home
- A phased return to work after absence
- Reduced workload or amended duties temporarily
- A quiet workspace or separate office
- Regular check-ins with a supportive manager
- Time off for medical appointments
- Exemption from performance targets during treatment
- Access to an Employee Assistance Programme (EAP)
What is "reasonable" depends on the size of your employer, the cost, and how effective the adjustment would be. Large employers are expected to do more than small ones.
Time off and sick pay
If you are too unwell to work due to your mental health, you are entitled to:
- Statutory Sick Pay from day one of absence (from 6 April 2026) — £123.25/week for up to 28 weeks, provided you meet the qualifying conditions
- Contractual sick pay if your contract provides for it (often more generous than SSP)
- The right not to be dismissed for taking sick leave, provided absence management procedures are fair
After 7 days of absence, your employer can request a fit note (Statement of Fitness for Work) from your GP. A fit note can state you are "fit for work with adjustments" rather than "not fit for work" — which can help you return with reasonable adjustments.
Protection from discrimination and harassment
If your mental health condition is a disability under the Equality Act:
- Your employer must not treat you less favourably because of your condition (direct discrimination)
- Your employer must not apply practices that put you at a disadvantage without justification (indirect discrimination)
- Your employer must not subject you to harassment related to your mental health
- Your employer must not victimise you for raising a complaint about discrimination
- Dismissal because of your mental health condition is disability discrimination and potentially automatically unfair
1
Disclose to your employer if it helps you access adjustmentsYou don't have to disclose your mental health condition, but without disclosure your employer cannot easily make adjustments. Consider telling HR or your manager what you need, even if you don't name the condition.
2
Request reasonable adjustments in writingPut your request in writing. Explain how your condition affects you at work and what adjustments would help. Your employer must consider this seriously.
3
Get a fit note from your GPA fit note can recommend specific adjustments. "Fit for work with adjustments" is more useful than "not fit for work" if you want to return with support.
4
Raise a grievance if your employer refuses adjustmentsIf your employer refuses reasonable adjustments without good reason, raise a formal grievance. Unreasonable refusal is disability discrimination.
5
Contact ACAS if you face dismissal or detrimentIf you are dismissed or treated worse because of your mental health, contact ACAS immediately. Time limits apply — 3 months less one day (6 months from October 2026).
6
Access your Employee Assistance ProgrammeMany employers provide free, confidential counselling through an EAP. Check your staff handbook or ask HR. You don't need to explain why you're using it.
Frequently asked questions
Does my employer have to make adjustments for anxiety or depression?
If your anxiety or depression has a substantial long-term effect on your daily activities (lasting 12+ months or likely to), it is likely a disability under the Equality Act and your employer must make reasonable adjustments.
Can I be dismissed for having mental health problems?
Dismissing you because of a mental health condition that amounts to a disability is disability discrimination. Even where there is a legitimate capability reason (long-term absence), your employer must follow a fair process, make reasonable adjustments, and consider alternatives before dismissing.
My employer says my performance is poor but I'm struggling with my mental health — what can I do?
Disclose your mental health condition to HR and request reasonable adjustments before or during any performance process. Your employer must consider whether the performance issue is connected to a disability and adjust the process accordingly.
I'm scared to tell my employer about my mental health — what are my options?
You can request adjustments without naming your condition. You can also ask your GP to state on a fit note that you need certain adjustments. ACAS and your trade union can advise on how to approach the conversation.
What is an Employee Assistance Programme?
An EAP is a confidential support service provided by many employers, offering counselling, legal advice, financial guidance and wellbeing support — usually free to employees. Check your staff handbook or ask HR.
Can my employer share information about my mental health with colleagues?
No — your health information is sensitive personal data under UK GDPR. Your employer can only share it with those who need to know and with your consent, or where strictly necessary.
What support is available if I'm in crisis?
If you are experiencing a mental health crisis, contact your GP urgently, call NHS 111 (option 2 for mental health), or attend A&E. Samaritans (116 123) and Crisis Text Line (text SHOUT to 85258) are free and available 24/7.
