No member of the fire department shall be absent from his regular hours of duty without permission.  In the event of sickness, if possible, notice shall be given to the officer in charge allowing him ample time to cancel days off, or make other necessary changes to fill the vacancy of any person reporting sick.  Any member of the force who is sick for as many as three (3) days must furnish the officer in charge a properly authenticated doctor’s certificate in support of his sickness.  Any absence for alleged sickness, if in fact sickness does not exist, will be grounds for dismissal from the force.
(1976 Code, § 7-47)
