No person who becomes a member of this retirement system following May 21, 1980 shall
be allowed to receive a retirement benefit or pension which is in part or in whole
based upon any service with respect to which the member is already receiving, or will
receive in the future, a retirement benefit or pension from another retirement system
or plan which is supported in whole or in part by public funds. As regards any member
who, following May 21, 1980, is covered by any other retirement system or plan which
is supported in whole or in part by public funds, credit for service shall only be
given in a year in which such member continuously fulfills his or her duties within
his or her position description other than during such member's regular hours of employment;
in such case the member shall not be precluded from receiving benefits from two (2)
retirement systems, each of which is supported by public funds. Further nothing herein
shall preclude a member from receiving at the same time benefits from this system
and the federal Social Security system.
