Sometimes referred to as the Wagner Act, the National Labor Relations Act was founded in 1935 as a U.S. federal law. The act restricts how employers can react to private sector employees who organize labor unions, participate in strikes, take part in collective bargaining, or any other form of group activity devised to support their work related needs. The act originally covered what were considered five unfair labor practices. These violations remain part of the code along with various other aspects that have since been added to the act. However, the National Labor Relations Act does not apply to employees who are protected by the Railway Labor Act. These workers include supervisors, domestic employees, agricultural employees, government employees on any level, and independent contractors.
