(a) A full-time civil service employee may request supplemental time off, during a term not to exceed 12 consecutive monthly pay periods in exchange for a commensurate reduction in pay. If the appointing power determines the request is feasible pursuant to section 599.833 of these regulations, the employee and appointing power shall enter into an agreement, stating the specific time or times that the supplemental time off may be used. The 12 monthly pay period term shall take effect at the beginning of a pay period.

(b) During the term of agreement, the participating employee's pay shall be reduced by a means of a fractional time base. Pay for hours worked, which are in excess of those required for the fractional time base elected but not in excess of those specified in the work week group for the position or classification, shall purchase supplemental time off credit. The Department shall approve which fractional time base options shall be made available for employee request.

(c) Supplemental time off credit may accumulate from month to month during the term of the agreement.

(d) Supplemental time off may be utilized in the pay period in which it is accrued.

(e) All supplemental time off shall be used as agreed. If supplemental time off cannot be used during the term of the agreement, then payment shall be made at straight time during the pay period immediately following the termination of the agreement, or the employee shall be credited with an equivalent amount of compensating time off, according to the discretion of the appointing power. When payment is by cash it shall constitute payment in full for services rendered and no retroactive adjustment of pro rata benefits or service credit shall be made. An employee who separates from state service without fault is entitled to a lump sum payment as of the time of separation for any accumulated supplemental time off. Such sum shall be computed by projecting the accumulated time on a calendar basis as provided in Government Code section 19839(a). An employee who separates from state service with fault is entitled to a lump sum payment as of the time of separation at straight time for any accumulated supplemental time off. The computation of such sum shall be based on actual accumulated time without projection as provided in Government Code section 19839(b).
