Okla. Stat. tit. 70, § 509.8

The procedure provided for herein for resolving impasses shall be the exclusive recourse of the organization. It shall be illegal for the organization to strike or threaten to strike as a means of resolving differences with the board of education. Any member of an organization engaging in a strike shall be denied the full amount of his wages during the period of such violation. If the organization or its members engage in a strike, then the organization shall cease to be recognized as representative of the unit and the school district shall be relieved of the duty to negotiate with such organization or its representatives.
