This Practice Note outlines the scope of an employer’s common law duty to take reasonable care for the safety of employees, with specific reference to the duty to provide safe premises, plant, systems of work and competent staff. It also explains the impact of Enterprise and Regulatory Reform Act 2013 (ERRA 2013) and the removal of civil liability for breach of most workplace health and safety regulations unless the relevant regulation expressly provides for it.

This duty of care extends to the employee’s physical and mental health. For further guidance on occupational stress cases, see Practice
