Shift workers, particularly those who work at night, may be at risk of ill health because shift work can disrupt our body clock (by interfering with the production of hormones by the body), disturb sleep and cause fatigue. In recognition of the particular risks to night workers, the Working Time Regulations include a right for these workers to receive free health assessments from their employer. Safewell offer Night Worker Health Assessment as part of our Occupational Health Service.
