Mental health and psychological wellbeing are just as critical to workplace safety as physical protection. In the UK, work-related stress, depression, or anxiety accounts for a significant portion of all work-related ill health.

Understanding how to manage mental health, conduct risk assessments, and support employees is essential for maintaining a productive, compliant, and healthy workforce. In this guide, we answer the most commonly searched mental health and workplace wellbeing questions.

Basics and Definitions

Mental health at work refers to the psychological wellbeing of employees. It involves how they think, feel, and cope with the pressures of their roles and workplace environment.

The Health and Safety Executive (HSE) defines stress as “the adverse reaction people have to excessive pressures or other types of demand placed on them.” It is not an illness itself, but if prolonged, it can lead to mental and physical ill health.

Psychological safety is the belief that one can speak up, report mistakes, or share concerns without fear of negative consequences or humiliation.

Legal Responsibilities and Compliance

Yes. Under the Health and Safety at Work etc. Act 1974, employers have a general duty to ensure, so far as is reasonably practicable, the health, safety, and welfare of all employees. This includes protecting them from psychological harm.

The Management of Health and Safety at Work Regulations 1999 require employers to assess the risks of work-related stress and implement measures to control those risks.

Yes. If a mental health condition has a long-term, substantial adverse effect on an individual’s ability to carry out day-to-day activities, it may be classed as a disability. This requires employers to make “reasonable adjustments.”

Identifying Signs and Symptoms

Signs can be emotional, physical, or behavioural. Look out for:

  • Increased irritability or mood swings.
  • Withdrawal from team activities.
  • Frequent headaches or fatigue.
  • Drop in work performance or missed deadlines.
  • Increased absenteeism or “presenteeism” (working while ill).

Burnout is a state of emotional, physical, and mental exhaustion caused by excessive and prolonged stress. It often manifests as a sense of cynicism, detachment, and a lack of accomplishment.

Risk Assessments and Control Measures

Similar to a physical risk assessment, this evaluates the “stressors” in the workplace. The HSE identifies six management standards:

  1. Demands: Workload, work patterns, and the environment.
  2. Control: How much say a person has in the way they do their work.
  3. Support: Encouragement and resources provided by the organisation.
  4. Relationships: Promoting positive working to avoid conflict.
  5. Role: Whether people understand their role and expectations.
  6. Change: How organisational change is managed and communicated.

Steps include:

  • Identify the risks (the stressors mentioned above).
  • Decide who might be harmed and how.
  • Evaluate the risks and take action to reduce them.
  • Record your findings.
  • Review the assessment regularly.

Support and Reasonable Adjustments

An EAP is a confidential benefit that provides employees with access to professional support, such as counselling, financial advice, or legal guidance, to help them manage personal or work-related problems.

Training and Competence

Mental Health First Aiders are employees trained to spot the early signs of mental ill health, offer initial support, and signpost the individual to professional help.

While not a specific legal certificate, managers should be competent in “soft skills”—knowing how to have difficult conversations, how to spot stress in their teams, and how to implement support measures.

  • Awareness training: Often takes half a day to a full day.
  • First Aider training: Usually a 2-day comprehensive course.
  • Refresher training: Recommended every 2–3 years to keep skills current.
