Time spent on leave without pay or shared leave counts towards completion of the employee's review period if the total time does not exceed one hundred seventy-four hours. If the total time on leave without pay or shared leave exceeds one hundred seventy-four the employer determines whether or not the time in excess of one hundred seventy-four hours will count towards completion of the review period. The granting of leave shall be in compliance with chapter 357-31 WAC and the Fair Labor Standards Act.
