Board Rule 4-28.	Trial Service applies when a current certified employee promotes or reinstates.  An appointing authority may require an employee who transfers to a different class with the same pay grade maximum to serve a trial service period.  The trial service period must not exceed six working months, except as provided in the “Time Off” chapter or when there is a selection appeal pending.  

A.	An employee who fails to perform satisfactorily during trial service shall revert to an existing vacancy in the previously certified class in the current department with no right to a hearing or, if there is no existing vacancy in the previously certified class in the current department, shall be accorded any retention rights to which the employee may be entitled under § 24-50-124, C.R.S. and/or Board Rule.  The appointing authority has discretion to administer corrective or disciplinary action instead of reversion.
