Under the Working Time Regulations, night workers must be offered a health assessment before starting work.

Employees don’t have to take up this offer though it must be made.

A night worker questionnaire is used to assess if there are any health risks associated with an employee working night shifts, taking into account that night work may expose the employee to increased stress, poor sleep patterns and worsening fatigue. Where any of the answers given highlight areas of concern regarding the employee’s fitness then they will be referred for a follow up telephone call. Following the telephone consultation, a fit note will be issued with the Occupational Health Advisors opinion on the Employees fitness for Night Shift work and any recommendations or adjustment they feel may be required
