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.
This guide is designed as an evolving resource. Its chapters link out to articles that go deeper into specific mechanisms — communication, masking, management, hiring or the work environment — as they are published.

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.
Those expectations are rarely written down. Answer quickly, calibrate your enthusiasm, understand that a request phrased as a question is in fact an instruction: nobody decided this, everybody complies. That is where differences in functioning turn into differences in judgement.
- 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.

That shift also means understanding the norm from which we observe differences
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.
Its most deceptive feature is that it works. Someone who masks well delivers, looks solid and triggers no alarm — until they stop. The manager then discovers a collapse where they saw a success story.
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.
None of these five practices requires extra resources. What they require is saying out loud what you assumed was obvious.
- State the success criteria before assigning the task
- Without criteria, the person works by guessing and the feedback arrives too late. Instead of “get me something short by Friday”, try: “by Friday I need a two-page summary that lets me choose between A and B”. The second sentence takes no longer to say; it avoids a full rewrite.
- Offer a choice of channel: written, spoken, asynchronous
- Some people think better in writing, others out loud. Imposing a single channel means assessing ease rather than competence. Content matters, not social form.
- Share the agenda and purpose of a meeting in advance
- A meeting with no stated purpose forces everyone to process information in real time while managing the social frame. Saying beforehand whether the point is to inform, decide or explore changes the quality of contributions — and usually shortens the meeting.
- Separate feedback on the work from judgement of the person
- “This document doesn't let me decide” and “you're not rigorous enough” do not produce the same effect, or the same correction. When feedback matters, writing it down lets it be re-read calmly, without the filter of tone and social setting.
- Ask “what do you need to work well?”
- “Is there a problem?” forces people to present themselves as struggling; few answer honestly. The first phrasing opens onto how the work is organised and requires no personal disclosure.

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.
Retention is rarely decided at the resignation. It is decided in the months when someone stops asking for adjustments because they understood these were treated as favours.
- 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.
The difference is simple: awareness changes what people think, a practice changes what they do the following Monday.
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.
