Neurodiversity, Conduct and Context: Lessons from the Madden Employment Tribunal Case

Recent Employment Tribunal decisions continue to highlight a growing gap in many organisations:

The gap between recognising neurodiversity and applying that understanding in real workplace situations.

The case of Madden v Commissioner of Police of the Metropolis brings this into sharp focus.

It is not a case about whether behaviour was appropriate. It is a case about how employers respond when disability may be part of the picture.

Case overview

Martin Madden, a long-serving employee of the Metropolitan Police, was dismissed for gross misconduct following a series of sexualised and inappropriate messages sent to colleagues.

There was no dispute that the messages caused offence.

However, the Tribunal found:

• The dismissal was unfair

• The employer had discriminated arising from disability under the Equality Act 2010

• Claims of indirect discrimination and failure to make reasonable adjustments were not upheld

A central issue in the case was that Mr Madden had ADHD, which affected areas such as:

• Social awareness and interpretation of boundaries

• Communication style

• Impulse control

The Tribunal accepted that the behaviour arose in consequence of that disability.

Where the employer fell short

This is where the case becomes particularly important for HR and business leaders.

The Tribunal did not find that the employer ignored the misconduct.

It found that the employer did not go far enough in understanding the context behind the behaviour.

Specifically:

• The link between ADHD and the behaviour was not fully explored

• The response was not considered proportionate in light of that link

• The dismissal fell outside the range of reasonable responses

  
  

In practical terms, the employer focused on what happened, but did not sufficiently examine why it happened.

Understanding discrimination arising from disability

Under section 15 of the Equality Act 2010, discrimination can occur where:

• An employee is treated unfavourably

• Because of something arising in consequence of their disability

• And the employer cannot justify that treatment as proportionate

This is a critical point.

The behaviour itself does not need to be intentional or directly caused by the disability. It is enough that there is a meaningful connection.

For employers, this creates a clear responsibility:

To actively explore that connection before making decisions.

The practical HR challenge

Many organisations have made real progress in raising awareness of neurodiversity.

But cases like this show where challenges still remain.

In disciplinary situations, we often see:

• Policies applied correctly

• Investigations completed thoroughly

• Outcomes that appear reasonable on the surface

Yet the process falls short because:

Neurodiversity is acknowledged, but not fully integrated into decision-making.

This is where risk sits.

What should employers be doing differently?

This case offers some very practical lessons.

When disability is, or could be, a factor:

1. Go beyond awareness

Recognising that someone is neurodivergent is not enough. You need to understand how that may influence behaviour in context.

2. Seek appropriate input

Occupational Health, medical advice, or specialist tools can provide valuable insight.

3. Consider alternatives

Dismissal should not be the default response where there is a disability-related explanation. Other options should be actively explored and documented.

4. Evidence your thinking

It is not enough to have considered disability. You must be able to show how it influenced your decision.

5. Focus on proportionality

The key legal test is whether your response is proportionate, not simply whether the behaviour breached policy.

This is not about excusing behaviour

It is important to be clear.

This case does not suggest that inappropriate behaviour should be overlooked.

Workplaces still need:

• Clear expectations

• Professional boundaries

• Safe environments for all employees

However, those expectations must be applied in a way that is:

• Informed

• Balanced

• Legally robust

The distinction is critical.

This case is about the quality of the employer’s response, not the acceptability of the behaviour itself.

A wider pattern

This case is part of a broader trend.

We are seeing increasing numbers of Employment Tribunal claims where:

• Neurodiversity is a factor

• Behaviour is misunderstood or misinterpreted

• Employers struggle to demonstrate proportionate decision-making

In many cases, the issue is not intent.

It is capability.

A lack of confidence in how to apply neurodiversity understanding in complex, real-world situations.

A more informed approach

Situations like this require a more structured and evidence-based approach.

This is where tools such as the Do-IT Workplace Profiler can play a valuable role.

Used appropriately, they can help:

• Identify strengths and challenges linked to neurodivergent traits

• Provide practical strategies and adjustments

• Inform more balanced and defensible decision-making

Importantly, they support a shift from assumption to evidence.

Final reflections

The key takeaway from this case is simple, but significant:

If disability is raised as a possible explanation, it must be genuinely investigated, documented and reflected in the outcome.

This includes appropriate use of occupational health or other external resources where needed.

For HR professionals and organisations, the next step in the neurodiversity journey is clear.

It is not just about awareness.

It is about application.

Because increasingly, that is where both organisational effectiveness and legal risk sit.
