(a) Any person who is concurrently employed by two or more participating subdivisions shall be considered a covered employee of each.
(b) Each employee-member shall make monthly employee contributions at the rate specified in the participation order of the particular employing subdivision upon all compensation paid that person by such employer. Each employing subdivision shall withhold the employee contributions required on account of the compensation paid such employee by such subdivision.
(c) The employee-member may receive only one month of credited service for any calendar month in which covered service was performed for two or more participating subdivisions. When determining an employee-member's retirement eligibility with respect to an employing subdivision, the credited service for a calendar month in which the employee-member was also performing covered service for another participating subdivision shall be counted as credited service performed for the employing subdivision for which retirement eligibility is being determined. When determining the retirement eligibility of an employee-member with respect to both subdivisions simultaneously, credited service is subject to the general rules of the system for recognizing and combining service among the several subdivisions but in no event may credited service for any calendar month be counted twice.
