A company union is a trade union which is located within and run by a company or by the national government, and is not affiliated with an independent trade union. Company unions were outlawed in the United States by the 1935 National Labor Relations Act, due to their use as agents for interference with independent unions, but company unions were and are common in many other countries. Some labor organizations are accused by rival unions of behaving like "company unions" if they are seen as having too close and cordial a relationship with the employer, even though they may be recognized in their respective jurisdictions as bona fide trade unions.
