Membership in the MSERS system is mandatory for nearly all state employees who are regularly employed on a part-time (minimum of half-time) or full-time permanent basis. If you are regularly employed in the performance of duties for the state you are considered a member-in-service. You remain a member-in-service until you separate from service by reason of retirement, failure of re-election or re-appointment, resignation or removal or discharge from your position or office that you hold.
