NLRB v. Mackay Radio & Telegraph Co., 304 U.S. 333 (1938), is a United States labor law case of the Supreme Court of the United States which held that workers who strike remain employees for the purposes of the National Labor Relations Act (NLRA). The Court granted the relief sought by the National Labor Relations Board, which sought to have the workers reinstated by the employer. However, the decision is much better known today for its obiter dicta in which the Court said that an employer may hire strikebreakers and is not bound to discharge any of them if or when the strike ends.
