Neurodiversity at work: understand, manage, transform
A practical guide for leadership, HR and managers who want to move beyond one-off awareness sessions. It draws on my experience as an autistic person and trainer, and on what neurodiversity reveals for the whole team, neurodivergent or not.

What neurodiversity actually covers
Neurodiversity means there are different ways of perceiving, processing information, focusing, communicating and getting tired. Autism, ADHD, dyslexia, anxiety: these are not boxes to tick, they are ways of functioning.
In a company, the useful question is not “who is neurodivergent?” but “what implicit expectations does our work environment impose, and who pays to meet them?” That shift is what makes the topic operational for a manager.
- Neurodivergent: a cognitive profile that diverges from the expected norm.
- Neurotypical: a profile that matches the implicit expectations of the environment.
- Neurodiversity: a collective reality, not a category of people.
The invisible cost of masking
Masking is the energy spent appearing to conform: controlling your tone, faking social ease, hiding sensory fatigue, not asking for clarification so you don't look slow. That energy is taken directly out of the work itself.
This cost never shows up as such in dashboards. It shows up elsewhere: quality dropping late in the day, meetings avoided, burnout leave, resignations framed as a “personal choice”, managers blindsided by a departure they never saw coming.
And masking is not limited to diagnosed people. As soon as an environment runs on unspoken rules, a large part of the team spends energy guessing what is expected.
Signals to watch for in a team
Before discussing accommodations, a manager gains from observing recurring friction. It usually says more about the environment than about the people.
- Instructions that always have to be reformulated afterwards.
- People who perform strongly alone and struggle in meetings.
- Fatigue that spikes on open-space or back-to-back meeting days.
- Feedback received as an attack because the criteria were never explicit.
- Talent leaving without visible conflict, with a vague reason.
Managing without a diagnosis: five concrete practices
A manager does not need to know who is neurodivergent, and should not ask. What they need are practices that reduce the implicit for everyone.
- State the success criteria of a task before assigning it, not after.
- Offer a choice of channel: written, spoken, asynchronous. Content matters, not social form.
- Share the agenda and purpose of a meeting in advance.
- Separate feedback on the work from judgement of the person, and write it down when it matters.
- Ask “what do you need to work well?” rather than “is there a problem?”.
For HR: hiring, onboarding, retention
Most HR processes assess the ability to present oneself, not the ability to do the job. An interview often measures social ease; a work sample measures competence.
Onboarding is the most expensive moment for a neurodivergent person: everything is implicit, from meeting norms to informal channels. Making the obvious explicit shortens ramp-up time for everyone.
- Send interview questions in advance: it tests thinking, not improvisation.
- Replace part of the interview with an exercise close to the real role.
- Document informal rules at onboarding (who decides what, how to interrupt, expected response times).
- Treat accommodations as options open to all, with no medical proof required.
Why a one-off awareness session isn't enough
A talk creates awareness. It does not change a meeting practice, a job ad template or an evaluation grid. Without translation into management gestures, the effect fades within weeks.
What lasts: an intervention that names lived experience, followed by a workshop where teams rewrite their own working rules, then a follow-up to settle whatever resisted.
Where to start, concretely
An organisation does not need a full programme to begin. It needs a first perimeter where the topic becomes tangible.
- Pick a pilot team and one practice to revisit (meetings or feedback).
- Create a collective moment where lived experience is named, with no obligation to disclose.
- Formalise three explicit rules decided by the team itself.
- Revisit them after six weeks and keep what held.
Frequently asked questions
- Do I need to know my team members' diagnoses?
- No. A diagnosis is private and is not required to act. The practices that help neurodivergent people — explicit criteria, choice of channel, agendas in advance — benefit the whole team.
- What's the difference between a keynote and a training session?
- The keynote creates collective awareness, starting from lived experience. The training turns that awareness into management practices: clarifying expectations, running meetings, feedback, onboarding.
- Does this only concern autistic or ADHD people?
- No. Starting from autism makes visible a tension that non-neurodivergent employees also live: the energy spent guessing unspoken expectations. The subject is the work environment, not a category of people.
- How long before there is an effect?
- On a small perimeter, a few weeks are enough to see clearer expectations and better meeting dynamics. Retention effects are measured over a longer horizon.
