Extra-Help employees, excluding term employees, do not accrue vacation credits.

If an extra-help employee is appointed to a regular position, such appointee shall receive credit for his/her extra-help period of service in computing accumulated vacation (up to a maximum accrual of 52 bi-weekly pay periods) and 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 he/she was not in a pay status, except where the absence from pay status was due to an approved leave of absence or a period during which the extra-help employee would not normally be scheduled to work.
