The retention standing of each competing employee shall be determined on the basis of tenure of appointment, length of creditable service, veterans preference, residency preference, and relative work performance, and on the basis of other selection factors as provided in these regulations. Together these factors shall determine whether an employee is entitled to compete with other employees for employment retention and, if so, with whom, and whether the employee is retained or released.
