2109.50 Compensatory Time.
   A Command Officer who has worked overtime shall be allowed to receive compensatory time off at the overtime rate, in lieu of pay, if he so elects. Upon request by the Command Officer, days off accumulated due to overtime shall be granted in accordance with the ten (10) per cent rule.
   Compensatory time off shall be granted whenever there are no more than ten (10) per cent of the Command Officers assigned to the shift requested the day off either vacation time or compensatory time. Request for vacation days will be considered first and then requests for compensatory time will be considered. However, when conditions permit, the Shift Captain or Bureau Head may, at his discretion, allow the individual Command Officer, in excess of ten (10) per cent, to take days off.
   In the event the Command Officer has not taken all compensatory time in excess one hundred (100) hours by April 30th of the year following the year in which the time was earned, then he shall be paid for all such hours in excess of one hundred (100) hours in the next regular pay check at the overtime rate.
