Employees being impacted by Reduction In Force may at management's opting, be considered for unoccupied (vacant) positions. Such employees must normally meet the minimum qualification requirements (although these can sometimes be waived) of positions they are being considered for.
The Office of Personnel Management has published two handbooks which provide an in depth discussion of all aspects of the reduction in force and transfer of function process. One handbook provides Guidance, and the other describes Required Procedures. For definitive guidance on any aspect of reduction in force, see the OPM Handbooks.
