ADHD at work

Your employment rights with ADHD

If your ADHD meets the Equality Act disability test, you have five distinct protections at work: against direct discrimination, indirect discrimination, discrimination arising from your disability (bad treatment for things the ADHD causes, like lateness, without justification), failure to make reasonable adjustments, and harassment or victimisation. Enforcement runs up a ladder: informal conversation, written grievance, free ACAS early conciliation, then an employment tribunal, where the usual time limit is 3 months less one day from the act complained of. Records win these cases; write things down as they happen.

Information only, not legal advice. Claim types from ACAS: disability discrimination; conciliation from ACAS; tribunal process from gov.uk. Checked 19 July 2026. For advice on your own situation, ACAS (0300 123 1100), Citizens Advice and law centres are free.

The five protections, in plain English

1. Direct discrimination

Treated worse specifically because of the disability: rejected, passed over or dismissed because you have ADHD.

"We need someone more reliable than an ADHD person" is the textbook case.

2. Indirect discrimination

A blanket rule that hits disabled people harder without good justification.

A rigid "no headphones, no exceptions" policy in a loud open-plan office.

3. Discrimination arising from disability

Treated badly not for the label but for something caused by it, unless the employer can justify it and adjustments were considered.

Disciplined for lateness that flows from ADHD, when flexible start times were never discussed.

4. Failure to make reasonable adjustments

The employer knew (or should have known) and did not make reasonable changes.

Written requests for meeting notes and staged deadlines ignored for months.

5. Harassment and victimisation

Degrading "banter" about the condition, or punishment for asserting your rights.

Being sidelined after raising an adjustments request is victimisation, itself unlawful.

The third one, discrimination arising from disability, is the workhorse of ADHD cases. It covers the gap between "we did not sack him for ADHD" and "we sacked him for the lateness his ADHD causes": the employer must show the treatment was justified, and a tribunal will ask what adjustments were tried first. If none were, that is usually where the case turns. The prerequisite for all five is meeting the disability definition, covered in is ADHD a disability in the UK?

The escalation ladder

Fix it informally: most problems are a manager who has not understood, not a villain. The adjustments conversation, done in writing, resolves the majority.
Written grievance: your employer's own procedure. Forces a formal response, creates the record.
ACAS early conciliation: free, required before most tribunal claims, and pauses the time limit while it runs. A conciliator tries to settle it without a hearing.
Employment tribunal: no fees to claim, designed to be navigable without a lawyer, usual limit 3 months less one day from the act complained of. Compensation for discrimination is uncapped, but the realistic goal at every earlier rung is a fixed job, not a payout.

Frequently asked questions

Can I be dismissed because of my ADHD?

Dismissal because of the disability itself, or for something arising from it without justification and without adjustments being properly considered, can be unlawful discrimination. Employers can still dismiss fairly for reasons unrelated to disability, and in genuine capability cases after adjustments have been made and reviewed. The order matters: adjustments first, conclusions after.

How long do I have to bring a tribunal claim?

Usually 3 months less one day from the act you are complaining about, which is short, and you must notify ACAS for early conciliation before lodging most claims (the conciliation window pauses the clock). If something serious has happened, take advice quickly rather than waiting to see if things improve; the deadline does not wait.

Do I need a lawyer?

Not necessarily. ACAS advice is free, early conciliation is free, tribunals are designed for unrepresented claimants and there are no fees to bring a claim. That said, for dismissal or complex discrimination cases, free advice from Citizens Advice, a law centre, or a union rep early on is worth a great deal. Check home or car insurance for legal expenses cover; many policies include employment disputes.

What should I be writing down?

Everything relevant, at the time: dates, what was said, who was present, copies of requests and responses. Discrimination cases are won on contemporaneous records. An email to yourself the same day is worth more than a perfect memory a year later. If you find writing hard, voice notes transcribed later count too.

Is a grievance worth it, or does it just make things worse?

A written grievance forces a formal response, creates the paper trail, and is usually expected before a tribunal takes a claim seriously. It can feel escalatory, but an employer that punishes you for raising one commits victimisation, which strengthens your position. Most disputes settle at or before this stage.
