Rights of Worker Upon Return from Leave. A worker returning to duty after an approved leave of absence without pay shall be returned to the same assignment held prior to the leave, providing the worker has met the conditions under which the leave was granted. If the assignment no longer exists, the District shall place the returning worker in another position as soon as one is available for which he/she is qualified and shall endeavor to place her/him in a position in the same salary range as the one held at the time the leave was granted. Time spent on unpaid leave of absence does not count toward seniority, salary increments, personal necessity leave credit, sick leave credit or vacation credit. Each month during which the worker is not in paid status will not count toward the anniversary date and will advance it by one month.
