For the vast majority of employees of state and local government, participation in a public pension plan and contributing toward the cost of the pension are mandatory terms of employment. Employee contributions provide a reliable and predictable stream of revenue to public pension funds and typically are based on a percentage of salary as specified in statute, most commonly between four and eight percent. More...
