New Jersey Statutes Title 34. Labor and Workmen's Compensation 34 § 13A-5.5

a. Notwithstanding any other provisions of law to the contrary, the majority representative and the public employer of public employees in an appropriate unit shall, where requested by the majority representative, negotiate concerning the subject of requiring the payment by all nonmember employees in the unit to the majority representative of a representation fee in lieu of dues for services rendered by the majority representative. Where agreement is reached it shall be embodied in writing and signed by the authorized representatives of the public employer and the majority representative.If no agreement is reached, the majority representative may petition the commission to conduct an investigation. If the commission determines during the investigation that a majority of the employees in the negotiations unit are voluntary dues paying members of the majority representative and that the majority representative maintains a demand and return system as required by subsection c. of this section and section 3 of P.L.1979, c. 477 (C.34:13A-5.6), the commission shall order the public employer to institute a payroll deduction of the representation fee in lieu of dues from the wages or salaries of the employees in the negotiations unit who are not members of the majority representative.

b. The representation fee in lieu of dues shall be in an amount equivalent to the regular membership dues, initiation fees and assessments charged by the majority representative to its own members less the cost of benefits financed through the dues, fees and assessments and available to or benefitting only its members, but in no event shall such fee exceed 85% of the regular membership dues, fees and assessments.

c. Any public employee who pays a representation fee in lieu of dues shall have the right to demand and receive from the majority representative, under proceedings established and maintained in accordance with section 3 of P.L.1979, c. 477 (C.34:13A-5.6), a return of any part of that fee paid by him which represents the employee's additional pro rata share of expenditures by the majority representative that is either in aid of activities or causes of a partisan political or ideological nature only incidentally related to the terms and conditions of employment or applied toward the cost of any other benefits available only to members of the majority representative. The pro rata share subject to refund shall not reflect, however, the costs of support of lobbying activities designed to foster policy goals in collective negotiations and contract administration or to secure for the employees represented advantages in wages, hours, and other conditions of employment in addition to those secured through collective negotiations with the public employer.
