The National Labor Relations Board (NLRB) is an independent federal agency of the United States government responsible for enforcing U.S. labor law in relation to collective bargaining, unfair labor practices, and private sector labor and management practices. It oversees labor relations and union elections in the private sector. The NLRB was established under the National Labor Relations Act of 1935 to protect employees' rights to organize, engage in collective bargaining, and address inequalities in bargaining power between employees and employers.
