Mr. Justice Douglas
delivered the opinion of the Court.
This case involves a controversy that started in 1956 between petitioner Local 165 and the Worcester Telegram and between petitioner Local 38 and the Haverhill Gazette. The two unions insisted that the collective bargaining agreements that were being negotiated contain clauses or provisions to which each employer objected. The controversy as it reaches here is reduced to two clauses: first, that the hiring for the composing room be in the hands of the foreman; that he must be a member of the union; but that the union “shall not discipline the foreman for carrying out written instructions of the publisher or his representatives authorized by this Agreement” ; and second, that the General Laws of the International Typographical Union shall govern the relations between the parties if they are “not in conflict with state or federal law.” The unions’ demand that these clauses be included in the agreement led to a deadlock in the negotiations which in turn resulted in a strike.
The employers filed charges with the Board, complaints were issued, the cases consolidated, and hearings held. The Board concluded that the demands for the two clauses and the strikes supporting them were violations of the Act. It found that a demand for a contract that included those clauses was a refusal to bargain collectively within the meaning of § 8 (b) (3) of the National Labor Relations Act, as amended by the Taft-Hartley Act, 61 Stat. 136,140-141,29 U. S. C. §158 (b) (3). It found that striking to force acceptance of those clauses was an attempt to make the employers discriminate in favor of union members contrary to the command of § 8 (b) (2) of the Act. It also found that striking for the “foreman clause” was restraining and coercing the employers in the selection of their representatives for the adjustment of grievances in violation of §8 (b)(1)(B) of the Act. 123 N. L. R. B. 806. The Court of Appeals enforced the Board’s order apart from features not material here. 278 F. 2d 6. The case is here on certiorari, 364 U. S. 878.
What we have said in Labor Board v. News Syndicate Co., decided this day, ante, p. 695, is dispositive of the clause which incorporates the General Laws of the parent union “not in conflict with state or federal law.” On that phase of the case the judgment below must be reversed.
