Based on the nature of the job and the skills of the appointee, the review period will be between twelve and eighteen months as determined by the appointing authority. At the time of the appointment, the appointing authority will inform the appointee in writing of the length of the review period. If an employee in a WMS review period accepts a nonpermanent position in a WGS position, upon return to the WMS position the employer may suspend the review period and allow the employee to resume where the employee left off or start the review period over.
