The National Labor Relations Act ("NLRA") in the federal law that regulates areas such as labor relations, collective bargaining and other matters between unions and employers. The NLRA was enacted by Congress in 1935 to safeguard the rights of employers and employees. The NLRA promotes labor unions and collective bargaining and prohibits employers from interfering with union matters and from retaliating against individuals who join unions. The NLRA has created the National Labor Relations Board ("NLRB"), an administrative agency that adjudicated disagreements between individual employers and labor unions. Generally, the NLRA applies to nearly all non-agricultural employers who take part in a business that in some way affects interstate commerce. The NLRB has two primary functions: 1) to prevent unfair labor practices and remedy the situation where necessary, and 2) to establish which unions are appropriate for individuals wishing to become part of a collective bargaining process.
