Employees are considered medically fit to continue working as long as their health does not affect their job performance.
In general, re-employed employees should be presumed to be medically fit to continue working. There is no need to send an employee for a medical check-up if he/she does not show any signs of being medically unfit for the job.
If they do, employers could send them for medical check-ups on a case by case basis, without having to send all eligible employees in the same job for medical check-ups. Employers could also send re-employed employees for medical check-ups if it is a job requirement that is applied to other employees with that job scope.
