Wherever in this chapter the rights of a member, because of membership in another retirement system, are conditioned upon reemployment within 90 days of termination of employment covered by a system under this chapter or another retirement system, with respect to such reemployment which occurs on and after January 1, 1976, such period shall be six months rather than 90 days.
This section shall also be applicable to members who were permanent employees of the state who were laid off because of a reduction in work force and whose break in service between retirement systems occurred prior to January 1, 1976, but not before April 1, 1970.
