Telling your employer you are neurodivergent

This guide is part of our complete guide to reasonable adjustments for neurodivergent employees.
You are not obliged to disclose
The barrier usually shows up before the conversation does: instructions that evaporate, an open-plan office that makes deep work impossible, feedback that lands as criticism of character rather than of work. Whether to explain why is entirely your decision. There is no legal duty on an employee to disclose a condition, no deadline, and no rule that says an application form or a probation review is the moment. Disclosure is a one-way door, so it is reasonable to weigh it carefully against the reception you expect.
It is also not all or nothing. You can tell one person and not another, name the barrier without naming the condition, or share a diagnosis with occupational health on the understanding that only the recommended adjustments reach your manager.
What disclosure actually does legally
The employer's duty to make reasonable adjustments under the Equality Act 2010 arises when they know, or could reasonably be expected to know, that a disabled person faces a substantial disadvantage. Silence therefore has a cost: an employer who has never been told about a barrier, and had no reasonable way of spotting it, is unlikely to owe adjustments for it. The neurodivergence hub covers how the Act's definition of disability applies to conditions such as ADHD, autism, dyslexia and dyspraxia.
Two details are worth holding on to. First, a formal diagnosis is not a precondition for the conversation; describing the effect on your work can be enough to put an employer on notice. Second, knowledge does not have to be delivered in legal language. An email saying you cannot follow verbal-only briefings and asking for written follow-ups can start the duty just as surely as a letter quoting the Act.
Deciding when and how much to share
A useful test is to work backwards from the adjustment. If what you need is written instructions and a quieter desk, the conversation can be about instructions and noise; the label adds little. If what you need involves occupational health, an Access to Work application or formal recognition that the Equality Act applies, more detail will usually be needed, and it is worth deciding in advance exactly what you are willing to put in writing.
Put the request itself in writing, keep a copy, and date it. If the response is good, the record does no harm. If it is poor, the record is what establishes when the employer knew.
What tends to go wrong
- Disclosing everything at once, under pressure, in a meeting called about something else. Timing and format should be yours.
- Sharing a diagnosis but never naming a barrier or an adjustment, which leaves the employer sympathetic and unhelpful in equal measure.
- Verbal conversations with nothing written down. If it is not recorded, it is hard to show the employer knew.
- Assuming disclosure to one manager travels with you. When managers change, restate the barrier and the agreed adjustments in writing.
If the reception is poor
A dismissive response does not switch the law off. Once an employer is on notice, refusing to consider adjustments, or treating you worse because you disclosed, can amount to discrimination. Keep records, restate the barrier in writing, and use the internal process before escalating; the neurodivergence hub explains how a fair adjustments conversation should run, which is a useful benchmark for judging the one you actually get.

Frequently asked questions
Do I have to tell my employer I am neurodivergent?
No. There is no legal duty on an employee to disclose a condition, and no deadline. The trade-off is that the employer's duty to make reasonable adjustments generally depends on them knowing, or reasonably being able to know, about the barrier you face.
Can I get adjustments without sharing my diagnosis?
Often, yes. Describing the barrier and the change that would remove it can be enough to put an employer on notice, and many effective adjustments need no medical detail at all. More formal routes, such as occupational health referrals, usually involve sharing more.
When is the best time to disclose?
There is no legally right moment. Working backwards from the adjustment you need is a sound approach: disclose when the barrier starts to matter, in writing, with a specific request attached, rather than waiting for a performance process to force the conversation.
What if my employer reacts badly to disclosure?
Treating someone worse because they disclosed a condition, or refusing to consider adjustments once on notice, can amount to disability discrimination under the Equality Act 2010. Keep written records, restate the request, and take advice from ACAS or an employment law specialist if it is not resolved.
