Previous Temporary Service. 704 In the event that a temporary employee in the bargaining unit becomes a permanent employee, he shall be credited with his continuous service as a temporary employee that is contiguous (excepting a break in service up to and including 14 calendar days) to his service as a permanent employee. However, the probation period will start on the first day of permanent employment. The employer may at its discretion reduce or eliminate the probationary period where an employee is performing the same job as the prior temporary assignment.
