During the years of participation in the other Nebraska governmental plan, the employee must have been a full-time employee, as defined in the Nebraska governmental plan in which the credit was earned.
(3) Any officer who qualifies for membership pursuant to subsection (1) of this section may not be disqualified from membership in the retirement system solely because such officer also maintains separate employment which qualifies the officer for membership in another public retirement system, nor may membership in this retirement system disqualify such an officer from membership in another public retirement system solely by reason of separate employment which qualifies such officer for membership in this retirement system.
