A company must have its workers get a doctor's health checkup to find out whether anyone is getting sick. The checkup is done when you join the company, and after that at least once a year. The company's job does not end with the checkup: it must also look at the results and respond afterwards.

When health checkups are done

  3. For special kinds of workExtra checkups at set intervals, such as every half year

Points

  • You get one when you join the company
  • After that, you get one once a year
  • If the results are a worry, the company asks a doctor for advice and reviews the work you do
For example: It is like the body measurements and health checks at school: you regularly check how your body is doing.
