①The purpose of this Act is to elevate the status of workers by promoting their being on equal standing with their employer in their negotiations with the employer; to defend the exercise by workers of voluntary organization and association in labor unions so that they may carry out collective action, including the designation of representatives of their own choosing to negotiate working conditions; and to promote the practice of collective bargaining, and procedures therefore, for the purpose of concluding collective agreements regulating relations between employers and workers.

②The provisions of Article 35 of the Penal Code (Act No. 45 of 1907) are to apply to collective bargaining and other acts of labor unions which are justifiable and have been performed for the attainment of the purpose of the preceding paragraph, provided, however, that in any case exercises of violence must not be construed as justifiable acts of labor unions.
