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 and their staff take steps to promote positive mental health and support those experiencing mental ill health.

The Acas framework for positive mental health at work

Acas has developed a new mental health framework for employers, employees and line managers. Acas Senior Adviser Abigail Hirshman talks about the Acas strategy for positive mental health at work.

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.

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

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 stress or anxiety from time to time.

Why is understanding and addressing mental health important?

People that feel good about themselves often work productively, interact well with colleagues and make a valuable contribution to the workplace.

A recent Chartered Institute of Personnel and Development study 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.

The study also found that, for the first time, stress is the major cause of long-term absence in manual and non-manual workers.

Promoting positive mental health in the 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.

For a step by step approach to help employers improve the mental health of staff and provide support for staff that experience mental ill health, go to Promoting positive mental health in the workplace.

Managing 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 how they can support staff experiencing mental ill health.

Dealing with stress in the workplace

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.

Acas research shows that two thirds of employees suffered stress and/or anxiety in the past year. Find out more about what they did to help themselves and what works in our policy paper pdf icon Stress and anxiety at work: personal or cultural? [324kb].

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.
