Should I tell my employer I'm autistic?

First, decide what you actually want from telling them

You're not legally required to tell your employer you're autistic, but disclosing is what triggers their duty to make reasonable adjustments and protects you from disability discrimination under the Equality Act 2010. So the first move is not the conversation, it's the decision: work out what you want disclosure to buy you. Most people want one of three things, and which one you want shapes who you tell and how. You might want specific reasonable adjustments (changes to how, when or where you work). You might want practical support through Access to Work, the government scheme that can grant funding for equipment, a job coach or a support worker. Or you might simply want to stop masking and be open about how you work best.

You do not need a formal diagnosis to be protected. The Equality Act defines disability as a physical or mental impairment with a substantial, long-term effect on your ability to do normal day-to-day activities, and autism can meet that test. The protection turns on the effect, not on holding a diagnostic letter, so this works whether you're diagnosed or self-identifying, though a diagnosis can make the impairment easier to evidence if it's ever questioned.

Then disclose in writing, naming what you need

Here is the part most guides skip. Your employer's duty to adjust only switches on once they know, or could reasonably be expected to know, that you're disabled. Until then they owe you nothing on adjustments, so not telling them does not just lose you support socially, it leaves them with no legal duty at all. That is why disclosing in writing matters: an email to your manager or HR puts the date on record and proves what they knew and when.

You can disclose at any stage, and what unlocks each one differs:

• At application or interview so you can ask for an accessible recruitment process, such as questions in advance.
• After a job offer so adjustments are set up before you start.
• Once you're in post, at any point, including when things start to feel unmanageable.

Keep it short and specific. Something like: "I'm autistic, and because of that I'd like to request reasonable adjustments under the Equality Act 2010, specifically [your two or three adjustments]." Naming the adjustments matters more than naming the diagnosis, because the law is about removing a substantial disadvantage, not about labels.

If adjustments are refused or you face detriment, escalate

If your employer refuses reasonable adjustments, or treats you worse after you disclose, that may be unlawful disability discrimination. Start with the internal route: raise it through the formal grievance procedure in writing, setting out what you asked for and what happened. If that doesn't resolve it, you can contact ACAS early conciliation (a free service that tries to settle disputes before a claim) before any employment tribunal claim. Telling your employer you're autistic is a personal risk-and-benefit decision, not a requirement, so weigh the support it unlocks against your own read of how it will land where you work.
