Extra-Help employees, excluding limited term employees, do not accrue vacation credits.
If an extra-help employee is appointed to a regular position, such appointee shall receive credit for their extra-help period of service in computing accumulated vacation (up to a maximum accrual of fifty-two (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 they were 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.
