Should I Tell My Boss I Have ADHD? A Psychologist’s Take on Workplace Disclosure

You mentioned your ADHD at work and got one of those looks. Or you decided not to mention it at all, because the risk felt too high. Or maybe you haven’t even been diagnosed yet — you just know something about how you function doesn’t quite match the template everyone else seems to follow.

The question of whether to disclose a mental health condition at work — particularly ADHD or another neurodevelopmental difference — is one I get asked about constantly. As someone who is both a clinical psychologist and openly neurodivergent, I’ve thought about this from both sides.

The disclosure dilemma is real.

Let’s be honest: disclosure is not always safe. In some workplaces, saying “I have ADHD” leads to understanding and accommodation. In others, it leads to being quietly passed over for projects, promotions, or trust. The research on workplace mental health disclosure is mixed, and it varies enormously by industry, role, and organisational culture.

What I tell my clients: disclosure is a strategic decision, not a moral one. You don’t owe anyone your diagnosis. You’re not being dishonest by keeping it private. The question isn’t “should I disclose?” but “what would I gain, and what might I lose?”

When disclosure tends to go well.

In my experience, disclosure works best when you have a specific, practical request (“I work best with written agendas before meetings” rather than “I have ADHD and need you to accommodate me”), when the workplace culture genuinely supports psychological safety, when your manager has demonstrated trustworthiness with sensitive information, and when you’re disclosing from a position of established competence.

What organisations can do better.

If you’re a leader or HR professional reading this, the burden shouldn’t be entirely on the individual. Organisations that build genuine psychological safety — not just the poster-on-the-wall version — create environments where neurodivergent employees can perform at their best without having to choose between authenticity and career safety.

This is something I work on with organisations through consulting and corporate programmes. It’s not about awareness campaigns. It’s about building systems that actually work for different kinds of brains.

If you’re navigating this question personally, or if you’re exploring whether ADHD might be part of your picture, a comprehensive assessment can give you the clarity to make informed decisions — about disclosure and everything else.
