Neurodiversity, Disability and Diagnosis: Helping Managers Navigate the Grey Area

Jun 29, 2026

Delivering training a few weeks ago something that kept coming up was the question:

"What should I do when an employee tells me they are neurodivergent but do not have a formal diagnosis?"

This can feel like a grey area. Managers may be concerned about legal obligations, fairness, consistency, or whether adjustments can be justified without medical evidence. At the same time, neurodivergent employees may be struggling with genuine barriers at work while facing long waiting lists, financial obstacles, or personal reasons for not pursuing a formal diagnosis.

The reality is that neurodiversity, disability, and diagnosis do not always fit neatly into organisational processes. Understanding this complexity can help managers create more inclusive workplaces while managing risk appropriately.

Neurodivergent and Disability Are Not the Same Thing

Neurodiversity describes the natural variation in how human brains think, process information, learn, communicate, and interact with the world. It encompasses conditions such as ADHD, autism, dyslexia, dyspraxia, dyscalculia, Tourette syndrome and others.

Not every neurodivergent person considers themselves disabled. Some view their differences as part of their identity and may experience little or no difficulty in certain environments.

However, many neurodivergent people do experience disability.

The social model of disability suggests that people are disabled not solely by their condition but by barriers in their environment. For example:

An autistic employee may thrive in a quiet workspace but struggle in an open-plan office with constant interruptions.
An employee with ADHD may perform exceptionally well when work is structured clearly but find disorganised systems overwhelming.
A dyslexic employee may excel verbally while encountering barriers in text-heavy processes.

In these situations, workplace design can either reduce or increase disability.

The Role of Formal Diagnosis

Formal diagnosis can be valuable for several reasons:

It may help individuals understand themselves better.
It can provide access to specialist support.
It may offer legal and organisational clarity.
It can help explain long-standing challenges.

However, diagnosis is not always straightforward.

Many adults face:

NHS waiting lists stretching into years.
Significant costs for private assessment.
Limited local availability of services.
Concerns about stigma or discrimination.
Cultural or gender biases that may have contributed to being missed in childhood.

For some employees, obtaining a diagnosis may simply not be possible in the short term.

As a result, many workplaces now encounter employees who identify as neurodivergent, have strong evidence of neurodivergent traits, or are awaiting assessment.

What Does the Law Say?

In the UK, the Equality Act 2010 protects individuals from disability discrimination.

Importantly, legal protection is not automatically dependent on possessing a formal diagnosis.

The key question is generally whether a person has a physical or mental impairment that has a substantial and long-term adverse effect on their ability to carry out normal day-to-day activities.

A diagnosis can provide evidence, but it is not the only evidence that may be considered.

This distinction often surprises managers. Many assume that no diagnosis means no obligation. In practice, organisations may still need to consider an individual's difficulties and whether reasonable adjustments could help.

Managers should not attempt to make legal determinations themselves. Instead, they should seek advice from HR, occupational health, or relevant specialists when needed.

Why Managers Get Stuck

Managers often find themselves caught between competing concerns.

On one hand:

They want to support employees.
They recognise genuine challenges.
They want to foster inclusion.

On the other:

They worry about setting precedents.
They fear accusations of unfairness.
They are unsure what evidence is required.
They may feel uncomfortable making decisions without a diagnosis.

This uncertainty can lead to one of two extremes:

Requiring formal diagnosis before considering any support.
Providing adjustments without any discussion or assessment.

Neither approach is ideal.

A Better Question: What Is the Barrier?

Rather than focusing exclusively on diagnosis, managers can shift the conversation towards workplace barriers.

Instead of asking:

"Can you prove you have ADHD?"

Ask:

"What aspects of your work are currently difficult, and what might help?"

This approach focuses on practical outcomes rather than medical gatekeeping.

For example:

An employee may report:

Difficulty concentrating in noisy environments.
Challenges prioritising competing tasks.
Problems processing verbal instructions.
Increased fatigue from constant meetings.

The discussion can then move towards possible solutions:

Noise-cancelling headphones.
Written follow-up instructions.
Clear prioritisation from managers.
Flexible working arrangements.
Meeting agendas in advance.

Many of these adjustments are low cost, low risk, and beneficial regardless of diagnosis.

The Value of a Human-Centred Approach

Managers do not need to become clinicians.

Their role is not to diagnose autism, ADHD, dyslexia, or any other condition.

Their role is to understand:

The impact on work.
The barriers being experienced.
Potential adjustments.
The effectiveness of support provided.

A human-centred approach acknowledges that people may be at different stages of their journey:

Formally diagnosed.
Awaiting assessment.
Self-identifying based on significant evidence.
Exploring whether neurodiversity may explain their experiences.

Supportive managers recognise that uncertainty does not eliminate need.

Creating Fairness Without Creating Barriers

One concern managers frequently raise is fairness.

"If we provide adjustments without diagnosis, where do we draw the line?"

The answer may be to focus on needs rather than labels.

Many organisations are moving towards workplace adjustment frameworks that consider:

The barrier.
The impact on performance and wellbeing.
The reasonableness of the adjustment.
Whether the adjustment is effective.

This creates consistency while avoiding unnecessary barriers to support.

It also reflects a broader principle of inclusive design: many adjustments that help neurodivergent employees benefit others too.

Clear communication, flexible working, predictable processes, and accessible information improve working conditions for a wide range of people.

What Good Management Looks Like

Managers navigating this grey area can ask themselves:

Have I listened without making assumptions?
Am I focusing on barriers rather than labels?
Have I explored practical adjustments?
Have I involved HR or occupational health where appropriate?
Am I applying organisational processes consistently?
Have I balanced business needs with employee wellbeing?

Most importantly:

Am I creating an environment where employees feel safe discussing their needs?

Final Thoughts

The intersection of neurodiversity, disability and diagnosis is rarely black and white.

Some neurodivergent employees will have formal diagnoses. Others will be waiting for assessment. Some may never pursue diagnosis at all. Yet they may still experience significant workplace barriers.

Managers do not need all the answers. They do not need to diagnose, validate or challenge an employee's identity.

What they can do is focus on the impact of workplace barriers and work collaboratively to identify reasonable, practical solutions.

Inclusion is not about becoming an expert in every neurodivergent condition. It is about recognising that people experience work differently and creating environments where those differences do not become unnecessary disadvantages.

When managers focus on needs rather than labels, the grey area becomes much easier to navigate.
