Mental Health Discrimination in the Workplace

Employees and workers in England and Wales are legally protected from discrimination based on mental health under the Equality Act 2010. This protection applies if a mental health condition meets the statutory definition of a disability - that is, a physical or mental impairment with a substantial and long‑term adverse effect on normal day‑to‑day activities. Mental health discrimination can take many forms, from unfavourable treatment and failure to adjust working conditions to harassment and victimisation. Understanding these rights, practical processes and how to respond are essential for individuals, employers and advisers navigating workplace disputes.

1. Mental Health as a Disability Under the Equality Act

The Equality Act 2010 defines disability broadly. A mental health condition such as anxiety, depression, bipolar disorder or post‑traumatic stress disorder (PTSD) can be a disability if it:

• Has a substantial adverse effect that is more than minor or trivial;
• Is long‑term - lasting or likely to last at least 12 months; and
• Affects everyday activities such as interacting with others, concentrating or coping with work demands.

It is not necessary to have a clinical diagnosis, though medical evidence often supports claims. Employers cannot normally ask about mental health before making a job offer, except in very limited circumstances.

2. What Counts as Mental Health Discrimination?

Discrimination occurs when someone is treated unfavourably because of their mental health condition regarded as a disability. Under the Equality Act, several unlawful patterns of conduct may arise:

2.1 Direct Discrimination

This is unfavourable treatment because of the disability. For example, refusing to consider an employee for promotion because of their known mental health condition would be unlawful.

2.2 Discrimination Arising From Disability

Where unfavourable treatment arises because of something connected with the disability (such as performance issues linked to anxiety), and cannot be objectively justified, this is also discriminative under section 15 of the Equality Act.

2.3 Indirect Discrimination

A workplace rule or requirement that disproportionately disadvantages people with mental health disabilities (for example strict attendance policies without flexibility) can be indirect discrimination unless justified as a proportionate means to achieve a legitimate aim.

2.4 Harassment and Victimisation

Unwanted conduct related to mental health that violates dignity or creates a hostile environment is unlawful. Treating someone poorly because they raised a grievance or made adjustments requests can amount to victimisation.

3. Employer Duties: Reasonable Adjustments

One of the core protections for mental health discrimination is the duty to make reasonable adjustments under section 20 of the Equality Act. When a disabled worker is placed at a substantial disadvantage by a job practice, workplace feature or lack of support, employers must take reasonable steps to remove or reduce that disadvantage. Adjustments should be individualised, practical and proportionate.

Examples of Reasonable Adjustments

Practical adjustments can include:

• Changes to working hours (flexible start/finish times, part‑time options).
• Altered responsibilities or task structures (break tasks down, reduce workload peaks).
• Supportive communication or supervision arrangements.
• Breaks for therapy or medical appointments and phased returns after sick leave.
• Temporary reallocation of duties during periods of acute difficulty.

Employers should consult with the employee to understand individual needs and document agreed adjustments. A failure to adjust when reasonable can itself be unlawful discrimination.

Employers' Discretion and Reasonableness

Not all requests must be granted; adjustments must be reasonable considering cost, disruption, effectiveness and the size of the employer. However, cost alone is not a sufficient reason to refuse if the change is practicable and beneficial.

4. Examples and Case Context

Tribunals in the UK have increasingly recognised subtle forms of discrimination linked to mental health or related conditions. For instance:

• Comments questioning an employee's organisational skills in the context of a neurodivergent condition were found to undermine dignity and constitute discriminatory conduct.
• Tribunal judgments have reinforced that failure to make reasonable adjustments and failure to address behaviour linked to disability can attract compensation for injury to feelings and financial loss.

These cases demonstrate that discriminatory treatment can be found even where comments or behaviours appear minor but stem from underlying disability factors.

5. Raising a Mental Health Discrimination Claim

5.1 Internal Procedures

An employee should raise concerns informally or through formal grievance procedures before initiating legal action. Detailed records of incidents, correspondence and adjustment requests strengthen any later claim.

5.2 ACAS Early Conciliation

Before presenting a claim to an employment tribunal, claimants must notify ACAS and engage in early conciliation. This process can help resolve issues without court action.

5.3 Time Limits

Employment tribunal claims normally must be presented within three months less one day from the date of the discriminatory act or last in a series of acts. Missing this deadline can lead to claims being dismissed unless there are exceptional reasons.

5.4 Remedies

If successful, a tribunal can award compensation for:

• Financial loss (such as loss of earnings).
• Injury to feelings (recognising the emotional impact).
• Recommendations to address discriminatory practices.

The amount of compensation depends on the severity and impact of the discrimination.

6. Practical Guidance for Employers and Employees

6.1 For Employers

• Develop and communicate mental health and reasonable adjustments policies.
• Train managers to recognise mental health issues and respond with sensitivity.
• Engage with affected employees to understand and implement appropriate adjustments.
• Review adjustments regularly, as needs may change.

6.2 For Employees

• Document all relevant incidents, discussions and requests for support.
• Disclose mental health conditions where appropriate to trigger protections.
• Use internal processes before tribunal claims.
• Seek support from HR, trade unions or legal advisers to understand options.

7. Common Questions

Does every mental health condition count as a disability?
Not every condition automatically qualifies. It must have a substantial and long‑term adverse effect on daily activities. Episodic conditions may qualify if symptoms are significant over time.

Can discrimination occur without a formal diagnosis?
Yes. The key focus is on the effects of the condition on day‑to‑day activities, not solely on clinical labels.

Can an employer ask about mental health at interview?
Generally, pre‑offer health questions are restricted to protect applicants from discrimination, with narrow statutory exceptions.

Summary

Mental health discrimination in the workplace falls under the broader umbrella of disability discrimination protected by the Equality Act 2010. When a mental health condition substantially and long‑term affects normal activities, employers must not treat affected workers unfavourably and must consider reasonable adjustments to mitigate disadvantage. Unlawful conduct can include direct discrimination, discrimination arising from disability, indirect discrimination, harassment and failure to make reasonable adjustments. Employees should engage internal procedures and ACAS early conciliation before tribunal claims, bearing in mind strict time limits. Employers should foster inclusive practices, proactively support mental health and implement agreed adjustments to reduce the risk of discrimination claims and enhance workplace wellbeing.
