Mental health is a crucial part of overall well-being, and for many, the workplace plays a significant role in shaping it. With most adults spending a large portion of their day at work, it’s essential that employers and employees alike recognise the value of creating and maintaining mentally healthy work environments.

Promoting positive mental health in the workplace isn’t just good for people, it’s good for business too.

Why mental health matters at work

Work-related stress, anxiety, and depression are among the most common causes of long-term sickness absence in the UK. According to the Health and Safety Executive (HSE), over 17 million working days are lost each year due to stress and poor mental health.

When mental health is neglected at work, the impact can include:

  • Increased absenteeism
  • High staff turnover
  • Reduced productivity and morale
  • Greater risk of conflict or burnout
  • Legal and reputational risks for the organisation

Benefits of a mentally healthy workplace

A workplace that prioritises mental health can see significant benefits across all levels of the organisation:

1. Increased Productivity

Employees who feel supported are more engaged, focused, and motivated in their roles.

2. Lower Absenteeism

A proactive approach to mental health can reduce the number of sick days taken and promote quicker recovery from periods of stress or illness.

3. Better Staff Retention

Companies that invest in employee well-being tend to retain talent more effectively and experience higher levels of job satisfaction.

4. Improved Team Culture

Open conversations around mental health foster trust, inclusivity, and collaboration among team members.

5. Reduced Risk of Workplace Disputes

Awareness and preventative strategies help minimise misunderstandings, grievances, and claims related to stress or mental health discrimination.

How employers can support mental health

Creating a mentally healthy workplace doesn’t require a huge budget—just a thoughtful and consistent approach. Here are some effective steps employers can take:

  • Promote open dialogue about mental health and well-being
  • Train managers to recognise signs of stress or burnout
  • Offer flexibility where possible, such as hybrid or remote work options
  • Encourage work–life balance by discouraging overtime and unrealistic workloads
  • Provide access to support services, such as counselling or Employee Assistance Programmes (EAPs)
  • Carry out stress risk assessments in line with legal requirements

The role of employers

Employees also play an important role in fostering a mentally healthy environment. This includes:

  • Speaking up early about stress or mental health concerns
  • Supporting colleagues who may be struggling
  • Making use of any available workplace resources or policies
  • Setting healthy boundaries between work and personal life

Mental health and UK Employment Law

Under UK law, employers have a duty of care to protect both the physical and mental health of their employees. If a mental health condition meets the definition of a disability under the Equality Act 2010, employers must make reasonable adjustments to help the individual continue working safely and effectively.

Failing to address mental health concerns can lead to legal risks, including claims of discrimination, unfair treatment, or constructive dismissal.

Mental health is just as important as physical health and businesses that understand this are better positioned for long-term success. By creating a workplace culture that values psychological well-being, employers not only protect their staff but also drive performance, loyalty, and growth.

A healthy workplace is a productive workplace.
