(40 ILCS 5/8-231)
(from Ch. 108 1/2, par. 8-231)
Employee who becomes participant in another fund.
Any participant in the fund who becomes a participant in any other
annuity and benefit fund, annuity and retirement fund or any pension fund
now or hereafter in operation in the city for the benefit of employees of
the employer, may elect to receive a refund or annuity from this fund in
the same manner as he would if he then resigned from his position in the
service and had not become a participant in such other fund. No credit is
allowed for any period of service as a participant in this fund for which
the employee receives credit in such other fund, and no annuity shall be
paid to such participant by this fund while he holds a position in the
service which entitles him to participation in such other fund.
If a participant in this fund is employed concurrently by an employer
whose employees are participants in a public retirement system created
under other Articles of the Illinois Pension Code as well as by the
employer as defined in this Article, any earnings from such other employer
during such period of concurrent employment shall not be considered for
annuity or benefit purposes under this Article.
