The initial determination as to whether the charges of unfair practices are justified, and, if so, what remedy is necessary to effectuate the purposes of this chapter, shall be a matter within the exclusive jurisdiction of the board, except that in an action to recover damages due to an unlawful strike, the board shall have no authority to award strike-preparation expenses as damages, and shall have no authority to award damages for costs, expenses, or revenue losses incurred during, or as a consequence of, an unlawful strike. Procedures for investigating, hearing, and deciding these cases shall be devised and promulgated by the board and shall include all of the following:
(a) Any employee, employee
organization, or employer shall have the right to file an unfair practice charge, except that the board shall not do either of the following: (1) issue a complaint in respect of any charge based upon an alleged unfair practice occurring more than six months prior to the filing of the charge; (2) issue a complaint against conduct also prohibited by the provisions of the agreement between the parties until the grievance machinery of the agreement, if it exists and covers the matter at issue, has been exhausted, either by settlement or binding arbitration. However, when the charging party demonstrates that resort to contract grievance procedure would be futile, exhaustion shall not be necessary. The board shall have discretionary jurisdiction to review a settlement or arbitration award reached pursuant to the grievance machinery solely for the purpose of determining whether it is repugnant to the purposes of this chapter. If the board finds that the settlement or arbitration award is repugnant to the purposes
of this chapter, it shall issue a complaint on the basis of a timely filed charge, and hear and decide the case on the merits; otherwise, it shall dismiss the charge. The board shall, in determining whether the charge was timely filed, consider the six-month limitation set forth in this subdivision to have been tolled during the time it took the charging party to exhaust the grievance machinery.
(b) The board shall not have authority to enforce agreements between the parties, and shall not issue a complaint on any charge based on alleged violation of such an agreement that would not also constitute an unfair practice under this chapter.
(c) The board shall have the power to issue a decision and order directing an offending party to cease and desist from the unfair practice and to take such affirmative action, including, but not limited to, the reinstatement of employees with or
without back pay, as will effectuate the policies of this chapter.
