In the interpretation of this chapter and in determining the jurisdiction and authority of the courts of the state of Washington, as such jurisdiction and authority are herein defined and limited, the public policy of the state of Washington is hereby declared as follows:

WHEREAS, Under prevailing economic conditions, developed with the aid of governmental authority for owners of property to organize in the corporate and other forms of ownership association, the individual unorganized worker is commonly helpless to exercise actual liberty of contract and to protect his or her freedom of labor, and thereby to obtain acceptable terms and conditions of employment, wherefore, though he or she should be free to decline to associate with his or her fellows, it is necessary that he or she have full freedom of association, self-organization, and designation of representatives of his or her own choosing, to negotiate the terms and conditions of his or her employment, and that he or she shall be free from interference, restraint, or coercion of employers of labor, or their agents, in the designation of such representatives or in self-organization or in other concerted activities for the purpose of collective bargaining or other mutual aid or protections; therefore, the following definitions of, and limitations upon, the jurisdiction and authority of the courts of the state of Washington are hereby enacted.
