If a doctor advises rest for 4 weeks in the medical certificate issued by him, it is considered professional misconduct. Rest is not to be advised for more than 15 days.

“Under no circumstances, a medical certificate should certify period of absence from duty, for a duration of more than 15 days. In case the medical condition of the patient is of such a nature that it may require further absence from duty, then in such case a fresh medical certificate may be issued.” (DMC/DC/F.14/Comp.647/2010 dated 21st July, 2010)
