Mental health at work

If you are suffering from a mental health condition or stress at work, UNISON can provide help and support
Last updated: 1 April 2026

Poor mental health can negatively affect employees' ability to work effectively, leading to stress, anxiety, and depression.  

Employers have a legal responsibility to provide a safe and healthy work environment, including mental health support.

If you are suffering from excessive stress at work which is affecting your mental health, speak to your line manager, occupational health or UNISON rep immediately. They will be able to help you access help and support.

If you are experiencing an urgent mental health crisis, you should call 999 for emergency services or go to your nearest A&E. 

For less urgent but still serious mental health needs, contact NHS 111 online or call 111 and select the mental health option, or contact your GP. The Samaritans can also be contacted for free on 116 123 or through their website.

Mental health at work

Mental health is a growing concern at UNISON. Motions raised at our National Delegate Conference over the past few years have shown a growing anxiety from our members on how our own mental health is affected by work.

Stress is a major pre-cursor to worsening mental health, and after years of austerity and being asked to do more with less, our members are at crisis point.  

Impact of mental health on organisations

Stress not only affects individuals, but also has an impact on productivity. A recent study by the Chartered Institute of Personnel and Development highlighted the impact that mental ill health can have on organisations. The study found that:  

  • 37% of sufferers are more likely to get into conflict with colleagues.  
  • 57% find it harder to juggle multiple tasks.  
  • 80% find it difficult to concentrate.  
  • 62% take longer to do tasks.  
  • 50% are potentially less patient with customers/clients.

Mental Health First Aid course

Mental Health First Aid is a training course designed to educate people to recognise the signs of people experiencing mental health issues. This allows them to provide immediate support and guidance, much like physical First Aid, but for mental health concerns.

There has been a huge drive in support for 'Mental Health First Aid' at work – not just from employers but from activists, as a solution to the growing concerns around managing mental health at work.

UNISON believes in the concept of immediate 'mental' as well as 'physical' first aid; however, the concept of 'physical' First Aid is much further forward, with legislation and organisational infrastructure behind it.

Mental health first aiders should also have some level of mental health support themselves, as well as recording options and supervision to ensure that they do not become overloaded due to role they are undertaking.

Learning

We know that learning something new is a great way to keep yourself well and can be a key part of aiding recovery from mental illness. Learning how you can support yourself and your colleagues can also be a great way of spreading the message about mental health at work and in our communities.  

All UNISON members can request free access to the Staff Skills Academy, which includes the following e-learning courses: 

Stress Management in the Workplace Certification

Reducing Stress (Techniques to Relax) Certification

Reducing Stress with Meditation and Visualisation Certification

Stress Management Certification
