Health assessments

Employers must offer workers a free health assessment before they become a night worker. They must also offer regular assessments throughout their workers’ employment. 

Workers do not have to accept.

How often workers get assessed depends on the results of the assessment for each worker.

The assessment can happen in different ways. For example, it might include a questionnaire written with input from a health professional.

If a health professional confirms that night working has affected a worker’s health, the employer must find them other suitable work, where possible.

Keep records

Employers must keep confidential records of:

  • the health assessments (keep for 2 years)
  • dates when assessments were offered (if a worker did not want one)
