The Fairfax County Employees' Retirement System was created in 1955, as what was then called the Supplemental Retirement System. While initially established for general County employees and non-Police Public Safety employees, select Fairfax County School's employees were added over the years. In 1974, when the Uniformed Retirement System was created, Firemen, Sheriff’s Deputies, Park Police, and Game Wardens moved from the Supplemental System into the Uniformed System. The Supplemental Retirement System name was changed to Employees' Retirement System in 2001.
