If your agency undergoes a major reorganization, reduction in force, or transfer of function, and a significant percentage of the employees will be separated, or will be reduced in pay, the head of your agency can ask the U.S. Office of Personnel Management (OPM) to permit early optional retirement for eligible employees.
If your agency gets approval to permit early optional retirements, eligible employees will be notified of the opportunity to retire voluntarily.
Information about Early Optional Retirement under CSRS is available here.
