What Is a Civil Service Retirement System?
A civil service retirement system is a retirement plan for civil employees, which are people who work for the government in positions ranging from postal employees to air traffic controllers. One notable example of such a plan is the Civil Service Retirement System (CSRS), established in the United States in 1920. The CSRS was replaced with the Federal Employees Retirement System (FERS) in 1987, but continues to provide benefits to people who were employed before FERS was established.
