Neurodivergence, mental health and wellbeing at work

Many organisations employ neurodivergent people, but working conditions do not always fit different needs. This guide sets out what neurodivergence means, what the evidence actually supports, and the changes that make a difference for employers in Europe.

What we mean, and what we do not

The language moves quickly and people use the same words for different things. Here is how we use them, so that the rest of this page can be read without ambiguity.

Neurodivergence
Having a brain that works in ways outside the most common patterns. It covers ADHD, autism, dyslexia, dyspraxia, Tourette syndrome and other differences. Many people describe themselves as neurodivergent without a formal diagnosis.
Neurodiversity
The full range of human brains, in the same way biodiversity describes the range of species. It is a fact about a population, not a trait of one person, so an individual is neurodivergent rather than neurodiverse. The idea was put forward by the Australian sociologist Judy Singer in the late 1990s.
Reasonable adjustments
Practical changes to how work is designed, organised or managed so a person can do the job on equal terms. Examples include written instructions, protected focus time and an agenda in advance. This practical term does not replace the legal conditions for an individual entitlement.
Not the same as mental illness
Neurodivergence describes differences and is not synonymous with mental illness. Mental health conditions can co-occur. The WHO notes that autistic people can have co-occurring conditions including depression and anxiety, and that autism can affect education and employment opportunities. This does not establish one mental health profile for all neurodivergent people.

The question for an employer is not whether someone is neurodivergent. It is whether the system they work in fits them at all.

What the evidence shows

For each point below: what the research says, what it means for an employer, and what we do about it. Every figure here is a published research finding, not a client result.

Research finding

Neurodivergent people are already part of working life

A global systematic review and meta-analysis published in the Journal of Global Health in 2021 estimated that, adjusted to the 2020 world population, 2.58% of adults have persistent ADHD and 6.76% have symptomatic adult ADHD, which the authors translate to roughly 140 million and 366 million adults. The WHO autism fact sheet states that about 1 in 127 people had autism in 2021.

What this means for employers

These population estimates show why different needs should be considered, not how many people in a particular team are neurodivergent. The two ADHD estimates use different definitions and should not be added together. A lack of disclosure proves neither an absence of neurodivergence nor a problem with workplace culture.

What WWS does

We do not begin by asking people to disclose. We look at how work is designed, organised and managed, and ask who that setup currently fits and who it quietly filters out.

Research finding

Participation needs more than a commitment

Germany's Inklusionsbarometer Arbeit 2025, published by Aktion Mensch with the Handelsblatt Research Institute, reports that 11.6% of working-age people with a recognised severe disability were unemployed on average in 2024, roughly double the general rate of 6%. Only a little over a third of employers under a quota obligation met the requirement to employ 5% of staff with a recognised disability, and about half of the three million people with a disability available to the labour market held a job, against an overall employment rate of 77%.

Note on this data: These measures use different populations and definitions. In particular, the unemployment rate and employment obligation concern people with a recognised severe disability (Schwerbehinderung). They do not measure neurodivergent workers as a separate group. Neurodivergence does not automatically mean a recognised severe disability.

What this means for employers

These figures show a participation gap, but do not establish its causes or an individual's capability. Accessible recruitment, appropriate adjustments and employee retention are practical starting points.

What WWS does

We treat inclusion as something you measure rather than something you claim: a baseline, an owner, and a date to check whether the change actually worked.

Research finding

Whether people ask for what they need is a system measure

Amy Edmondson's 1999 field study of 51 work teams (Administrative Science Quarterly, 44(2)) found an association between psychological safety and learning behaviour. Google's Project Aristotle reviewed more than 180 teams and identified psychological safety among five key dynamics. Neither study focused specifically on neurodivergent employees.

What this means for employers

Asking for an adjustment can require trust. People may fear a judgement about their competence. This research offers a useful lens, not proof of how every support request will develop.

What WWS does

We measure whether people can speak up before recommending anything, then read the answers as evidence about who the current setup serves, not as a verdict on the people answering.

Illustrative example

A team that moves from back-to-back video calls and an open-plan desk to two protected focus mornings a week, a written agenda circulated in advance and notes afterwards, has not hired anyone or bought anything. The change is to how the work is arranged. This is a description of a common pattern, not a record of a specific client.

Where it shows up in the six pillars

Neurodivergence is not a separate topic for one network group to own. It runs through four of the six pillars, the same ones that decide whether anyone else thrives here.

Seven practical moves

These are the changes we recommend starting with. None of them require a diagnosis from anyone.

  1. Move 1

    Fix the job before the person

    Look at workload, task sequencing, deadlines and meeting load first. Most of the friction people describe is a design problem, not a personal deficit.

  2. Move 2

    Make adjustments easy to ask for

    One named contact, a short written route, a decision within a set time. Do not require someone to explain a diagnosis to get a change to how work is arranged.

  3. Move 3

    Check what your hiring process filters out

    Timed tests, unstructured interviews and open days can screen out capable candidates. Offer written instructions, extra time, and the chance to see questions in advance.

  4. Move 4

    Train managers on the practical, not the clinical

    Managers do not need to diagnose anyone. They need to know what to change, who to ask, and how to keep the conversation about the work.

  5. Move 5

    Treat the environment as a lever

    Noise, lighting, interruptions and how much of the day is left unbroken are concrete choices with a cost you can see in output and absence.

  6. Move 6

    Say what you offer before anyone asks

    Publish the adjustments you will make and how to request them. A list that exists but is hidden in a policy folder helps no one.

  7. Move 7

    Measure whether it worked

    Run anonymous pulse checks on workload, clarity and whether people can ask for help. Track which adjustments were made and whether the person stayed.

Common questions

What is neurodivergence?
Neurodivergence describes brains that work in ways outside the most common patterns, including ADHD, autism, dyslexia, dyspraxia and Tourette syndrome. It is a description of difference, not of illness or of lower ability.
Is neurodivergence a mental health condition?
Neurodivergence is not synonymous with mental illness. Conditions such as depression and anxiety can co-occur, for example in autistic people. Unsuitable working conditions can add strain; not everyone has the same experience.
Should employees have to disclose a diagnosis?
We would advise against making disclosure the price of support. If someone needs a change to how work is arranged, that request should be answerable on its own merits. Diagnosis should only be needed where a specific legal or funding route requires it.
What are the legal duties in Germany?
Under section 154 SGB IX, employers with an annual average of at least 20 monthly workplaces counted under the statutory rules must generally employ people with a recognised severe disability in at least 5% of those workplaces. Obligated employers with fewer than 40 workplaces must employ one, and those with fewer than 60 must employ two. Equivalent-status workers are also covered by the relevant rules. Paying a compensatory levy does not discharge the obligation. Neurodivergence is not automatically a recognised severe disability: section 2 generally requires a degree of disability of at least 50, while a degree of 30 or 40 may qualify for equivalent status subject to further conditions. Sections 164(4) and 151 provide qualifying employees with rights to disability-appropriate work design and aids, subject to statutory limits including reasonableness, disproportionate expenditure and conflicting protective rules. The AGG prohibits disability discrimination without necessarily requiring recognised severe disability status. Other European countries have different rules. This is general guidance, not legal advice.
How do I know whether my workplace is excluding neurodivergent people?
Look for the pattern rather than the individual case: the same people asking for the same clarifications, the same team always overloaded, people leaving in their first year, and an adjustments process with no requests in it. An anonymous check on workload, clarity and psychological safety usually shows the picture.
Does a neurodiversity programme improve performance?
We would not promise a performance gain from a policy document, an awareness week or a poster. Where we see value is in the unglamorous version: clearer briefs, less meeting load, fewer interruptions, managers who can adjust without drama. Those help everyone, and they are the same changes a psychosocial risk assessment points to.
