(2) Any employee who qualifies for membership in the retirement system pursuant to subsection (1) of this section may not be disqualified for membership in the retirement system solely because such employee also maintains separate employment which qualifies the employee for membership in another public retirement system, nor may membership in this retirement system disqualify such an employee from membership in another public retirement system solely by reason of separate employment which qualifies such employee for membership in this retirement system.
