An employee who is appointed to a WMS position from a WGS position in the same agency while serving a probationary or trial service period in the same or similar occupational field may serve the trial service or probationary period concurrently with the review period. At the discretion of the employer, the employee may attain permanent status in the previous job classification once the original probationary or trial service period concludes.

If the positions are in the same or similar occupational field, the employer may allow for some or all of the time served in the probationary or trial service period to count towards the review period.
