Disciplining an employee with mental health issues UK is a sensitive area where employment law and practical management intersect in complex ways. I’m John Bloor at EBS Law, and I’ve advised many employers who believe they are doing the right thing but a mental health issue adds complication. My aim here is to help you navigate what you should consider, what you must not overlook and how to approach the process in a fair and legally sound way.
Why disciplining an employee with mental health issues UK requires care
When you face performance or conduct concerns, the default may be to rely on your usual disciplinary policy. However, when an employee is also struggling with a mental health issue, the standard approach may not be appropriate. Under the Equality Act 2010 certain mental health conditions may count as a disability and deliberately or inadvertently ignoring this possibility may lead to discrimination claims.
For example: I recently worked with a small employer whose star performer suddenly started missing deadlines. They initiated a disciplinary meeting without asking about underlying issues. Later it emerged the employee was experiencing anxiety and depression. The delay in exploring that made the employer vulnerable. Early awareness might have enabled adjustments rather than discipline.
Key steps when disciplining an employee with mental health issues UK
Firstly, gather your facts. Before any meeting, it’s wise to:
– Investigate the performance or conduct concerns and get the full picture.
– Consider whether there are signs of a mental health issue (changes in behaviour, increased absence, withdrawal).
– Ask whether any health matter is impacting the employee’s work and whether support or adjustments are needed.
When you move to a disciplinary meeting:
– Keep the tone respectful and open. Acknowledge the possibility of a health issue.
– Allow the employee to explain and respond.
– Ensure they know they can be accompanied (companion rights still apply).
– Document every stage clearly from the investigation, the meeting, the decision and any follow-up.
Remember this is not simply “business as usual”. The law requires you to make reasonable adjustments if the condition qualifies as a disability under the Equality Act. Failing to do so before or during a disciplinary process may tip the balance against you.
Reasonable adjustments and how they fit with disciplining employee with mental health issues UK
Having determined that a mental health condition might be present, you should consider adjustments. These could include:
– Altered working hours or breaks.
– Modified duties or removal of particular stressors.
– Additional support, counselling or an occupational health referral.
– A phased return to work if long-term absence has occurred.
You must balance the business need with fairness. In one case I advised, an employer insisted on full weekly hours immediately after a long absence. The Tribunal found that a phased return would have been reasonable and penalised the employer accordingly. You can maintain standards but you must show you have genuinely considered adjustments. That is key when disciplining an employee with mental health issues UK.
Disciplinary outcomes and avoiding unfair treatment
Not every case of poor performance linked to mental health means you must accept under-performance indefinitely. But if you reach the stage where you are considering disciplinary sanctions or even dismissal, you must apply the same fair procedure as you would otherwise and more. If the employee’s mental health amounts to a disability, dismissal without exploring adjustments and support may be unfair de facto.
In the UK context, you must ensure that:
– The reason for discipline is clearly linked to a legitimate issue (conduct or capability).
– You have followed your procedure fairly (investigation, meeting, right to appeal).
– You have documented the process and acted in a way a reasonable employer might.
– You have considered the possibility of discrimination under the Equality Act.
A misstep here may result in claims such as disability discrimination or unfair dismissal. According to guidance from ACAS, employers have a duty of care to treat mental health issues seriously and to make reasonable adjustments.
What you should do right now
– Review your disciplinary policy: does it explicitly reflect mental health considerations?
– Train your managers to spot changes in behaviour and understand when adjustments may be needed.
– Ensure you have up-to-date records of any support or adjustments offered.
– If you are about to initiate discipline with an individual you suspect has a mental health issue, seek legal advice early. At EBS Law we frequently support employers in exactly this situation.
Conclusion
In short: disciplining an employee with mental health issues UK is not necessarily a barrier to maintaining performance standards. But it does demand a more thoughtful, documented and sensitive approach. I’ve seen the difference when employers act early, show understanding, and keep discipline fair and consistent. A mis-step can be costly, both legally and reputationally. At EBS Law I’ve advised both small and large employers in this area — the message is clear: act with care, record every step and don’t assume the usual process is enough.
