Notwithstanding any provisions of the "New Jersey Employer-Employee Relations Act," P.L. 1941, c.100 (C.34:13A-1 et seq.), or any other law to the contrary, if an employee who does not pay dues to a majority representative requests that the majority representative represent the employee in arbitration proceedings to enforce the terms of the collective negotiations agreement between the majority representative and the public employer, including arbitration proceedings involving the resolution of disciplinary disputes, the majority representative may charge an employee for the cost of representing the employee in the arbitration proceedings, and may decline to represent an employee in the arbitration unless the employee agrees to pay for the cost of the representation.
