The policy of the state is to encourage voluntary settlement of labor disputes in municipal employment through the procedures of collective bargaining. If the procedures fail, the parties should have available to them a fair, speedy, effective, and above all, peaceful procedure for settlement, including, where a deadlock exists after negotiations and after mediation by the commission, a procedure for the resolution of the dispute by interest arbitration.
