When a permanent WMS employee is appointed to a WMS position and reverted during the review period, the current employing agency at the time of reversion must place the employee in a vacant funded WMS position for which the employee is qualified, and that is comparable to the employee's position and salary prior to the last WMS appointment. If no vacant funded positions are available, the agency must place the employee in a WMS position for which the employee is qualified and which is similar to the employee's previous position and salary. If the reversion of the employee causes the total number of employees to exceed the total number of positions to be filled, the employer may implement a layoff.
