FERS Information. Congress created the Federal Employees Retirement System (FERS) in 1986, and it became effective on January 1, 1987. Since that time, new Federal civilian employees who have retirement coverage are covered by FERS.
Before FERS and CSRS Offset became effective on Jan. 1, 1987, an employee who initially obtained a federal position eligible for retirement coverage between Jan. 1, 1984 and Dec. 31, 1986 was given temporary retirement coverage called CSRS Interim.
