Final answer:
The National Labor Relations Board (NLRB) is the board tasked with conducting union elections and preventing unfair labor practices. It enforces laws to protect workers' rights to organize, represents workers in disputes, and ensures compliance with labor laws.
Step-by-step explanation:
The board responsible for conducting elections to determine union representation and interpreting and applying law against unfair labor practices is the National Labor Relations Board (NLRB). The NLRB was established to enforce labor laws and ensure the protection of workers' rights to organize and bargain collectively. It handles cases related to unfair labor practices, supervises elections for labor union representation, and enforces the rules established by the Wagner Act which outlines the legal framework for labor relations. Additionally, it addresses disputes between unions and employers, ensuring that firms follow established procedures for union establishment.
During periods of national emergency, such as World War I and World War II, the National War Labor Board (NWLB) was established to address labor disputes and prevent work stoppages that could affect the production of essential wartime supplies. Overall, the NLRB and related agencies have played a pivotal role in shaping labor-management relations and safeguarding workers' rights.
