The main purpose of this legislation, known as the Federal Retirement Fairness Act, is to allow certain temporary federal employees to count their service time toward retirement benefits under the Federal Employees Retirement System (FERS). This change aims to provide fairer retirement benefits for those who have worked in temporary positions since December 31, 1988. Key provisions of the Act include the removal of the restriction that only service performed before January 1, 1989, could be credited toward retirement.
