What should a staff member do to in order to report the days they are out sick?

Staff members have an obligation to inform their supervisors as soon as possible of any absences due to illness or injury, and promptly submit the medical certificate or report, if required, to certify their sick leave. If you were unable to obtain the necessary certification at the early stage of your absence on sick leave, you have up to 20 working days following the initial absence from duty to do so.
