When an employee who has been working as extra help is appointed to a permanent position such appointee may receive credit for such extra help period of service in computing accumulated sick leave, provided that no credit shall be given for service preceding any period of more than twenty-eight (28) consecutive calendar days in which an employee was not in a pay status.
If an employee who has unused sick leave accrued is laid off and subsequently re‑employed in a permanent position, such sick leave credits shall be restored upon reemployment. The employee shall not have any portion of sick leave credits restored for which they received compensation at the time of or subsequent to the day of layoff.
