Mental health in the workplace

The Government's Department of Health advises that one in four of us will experience mental ill health at some point in our lives. It is therefore important that employers, managers and employees take steps to promote positive mental health, recognise the warning signs and support anyone experiencing mental ill health.

The Acas framework for positive mental health at work

The Acas framework for positive mental health at work recommends that responsibility for positive wellbeing and productive workplaces is shared between employers, managers and employees.

What is mental health?

Mental health includes our emotional, psychological, and social well-being. It affects how we think, feel, and act. It also helps determine how we handle stress, relate to others, and make choices.

People that have good mental health are more likely to:

  • work productively
  • interact well with colleagues
  • have good attendance levels
  • make a valuable contribution to the workplace.

Yet most people's mental health will not just be continuously good. Usually it will rise and fall depending on pressures and/or experiences in their life. A person may therefore feel in good mental health generally but also experience mental ill health from time to time.

Mental ill health can range from feeling 'a bit down' to common conditions such as anxiety and depression to more severe and far less common conditions such as bipolar disorder or schizophrenia.

The impact of mental ill health at work

The estimated cost of mental ill health to UK employers each year is between £33 billion and £42 billion.

Additionally a Chartered Institute of Personnel and Development study highlighted the impact that mental ill health can have on organisations. It 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.

Employers should therefore be taking steps to support staff and promote positive mental health in their workplace.

What can employers do to promote positive mental health in their workplace?

Promoting positive mental health in your workplace can be hugely beneficial. Staff with good mental health are more likely to perform well, have good attendance levels and be engaged in their work.

However it can be difficult for employers to know what they should do. Our step by step guide can help employers create a working environment that encourages better mental health and provide appropriate support to any employee that experiences mental ill health.

For more information, go to Promoting positive mental health in the workplace.

How should managers manage staff experiencing mental ill health?

Managers should be confident in supporting staff experiencing mental ill health. It is important that managers are able to spot the signs of mental ill health, know how to approach conversations sensitively and support their team member if they are experiencing mental ill health.

Managers wanting help and advice should go to the Acas guidance on Managing staff experiencing mental ill health.

Dealing with stress in the workplace

Acas research pdf icon Stress and anxiety at work: personal or cultural? [324kb] indicates that two thirds of employees suffered stress and/or anxiety in the past year.

Reducing work-related stress can be hugely beneficial to an employer - reducing absence levels and improving overall performance. Employers also have a legal obligation to ensure the health, safety and welfare of their employees.

Organisations should be thinking about the causes of workplace stress, how to reduce them in their workplace and how best to support staff when they do experience stress.

For more information, go to Dealing with stress in the workplace.

Workplace Anxiety & Work Related Anxiety

Anxiety is a feeling of worry, fear, nervousness or unease about something. Employers and managers should understand what can cause anxiety and what signs may indicate a team member is experiencing anxiety.

For more information, go to Workplace Anxiety & Work Related Anxiety.
