Why manage work-related stress and mental well-being?

There are many good reasons for tackling stress in the workplace, and everyone has a part to play, at every level of the organisation.

The legal reason

While there is no legislation that specifically mentions work-related stress, under The Health and Safety at Work Order (NI) 1978 employers have a duty to ensure so far as reasonably practicable the health and safety of their employees at work.

Additionally there are duties placed upon employers to assess risks to health. These duties are contained within The Management of Health and Safety at Work Regulations (Northern Ireland) 2000. In the past these duties focused on physical well-being but is now recognised that it applies equally to psychological health and well-being.

In 2004 the Health and Safety Executive developed the management standards which are a set of principles to help employers comply with the law.

Over the last number of years there have been a number of successful civil actions taken by employees for work-related stress.

The moral/ethical reason

Managing the causes of work-related stress prevents ill health. There is now convincing evidence that prolonged periods of stress, including work- related stress, have an adverse effect on health.

Research provides strong links between stress and:

  • physical effects such as heart disease, back pain, headaches, gastrointestinal
  • disturbances or various minor illnesses
  • psychological effects such as anxiety and depression, loss of concentration
  • poor decision-making

Stress can also lead to other behaviours that can have an adverse effect on psychological and physical health and well-being, for example:

  • social withdrawal
  • aggressive behaviour
  • alcohol/drug abuse
  • eating disorders
  • working long hours

The financial reason

In 2019/20 a total of 17.9 million days were lost due to work-related stress, depression or anxiety (Labour Force Survey)

Each case of work-related stress leads to an average of 21.6 working days lost. There is also presenteeism, which is a reduction of productivity as high as 33% that occurs when employees come to work but function at less than full capacity because of stress/ill health.

In 2019/20 stress accounted for 51% of all work related ill health cases and 55% of all working days lost due to ill health.

Research has shown work-related stress to have adverse effects for organisations in terms of:

  • employee commitment to work
  • staff performance and productivity
  • accidents caused by human error
  • staff turnover and intention to leave
  • attendance levels
  • staff recruitment and retention
  • organisational image and reputation
  • potential litigation

It is also worth thinking about the impact that work-related stress could have on your unit or team. For example, losing one colleague for an extended period with a stress-related illness can have a dramatic impact on the workload and morale of the rest of the team.

By taking action to manage the causes of stress in your workplace, you can prevent or reduce the impact of these problems on your organisation and bring about business benefits.
