Pennsylvania Statutes Title 53 P.S. Municipal and Quasi-Municipal Corporations § 881.117. Part-time employes

(a)(1) All existing part-time employes not enrolled in the pension plan shall have the right to elect to participate in the pension plan.  A member's election to participate in the pension plan under this subsection must be made in writing and received by the municipality before July 1, 2005, and shall be irrevocable.

(2) Existing part-time employes not enrolled in the pension plan who elect to participate in the pension plan under this subsection must pay into the system all member contributions plus the regular interest that would have been credited to those contributions had they participated in the system from their date of hire.  Failure of the part-time employe to make such contributions and regular interest payments as determined by the administrator of the system shall be considered the same as if the part-time employe had chosen not to participate in the system.  All other amounts required to be contributed to the pension plan as a result of their election to participate shall be paid by the municipality.
