(1) It is the public policy of the State of Oregon that where the right of employees to strike is by law prohibited, it is requisite to the high morale of such employees and the efficient operation of such departments to afford an alternate, expeditious, effective and binding procedure for the resolution of labor disputes and to that end the provisions of ORS 240.060, 240.065, 240.080, 240.123, 243.650 to 243.782, 292.055 and 341.290, providing for compulsory arbitration, shall be liberally construed.

(2) When the procedures set forth in ORS 243.712 and 243.722, relating to mediation of a labor dispute, have not culminated in a signed agreement between the parties who are prohibited from striking, the public employer and exclusive representative of its employees shall include with the final offer filed with the mediator a petition to the Employment Relations Board in writing which initiates binding arbitration for bargaining units with employees referred to in ORS 243.736 (1). Arbitration shall be scheduled by mutual agreement not earlier than 30 days following the submission of the final offer packages to the mediator. Arbitration shall be scheduled in accordance with the procedures prescribed in ORS 243.746.
