Which agency regulates labor relations specifically in the airline industry?

The National Mediation Board (NMB) is the agency that specifically regulates labor relations within the airline industry. Established to oversee the implementation of the Railway Labor Act, the NMB's primary role is to facilitate the resolution of disputes between airlines and their employees, including union organization and collective bargaining processes.

In the context of the airline industry, the NMB provides critical support for maintaining stable labor relations by mediating disputes and ensuring fair practices in workplace negotiations. Its focus on the unique aspects of the airline sector differentiates it from other agencies that deal with labor relations in broader contexts, making it indispensable for the airline industry specifically.

The other agencies listed serve different functions: the FAA (Federal Aviation Administration) focuses on aviation safety and regulation, the NLRB (National Labor Relations Board) deals primarily with labor relations in the private sector outside of the railway and airline industries, and the DOT (Department of Transportation) oversees various transportation-related regulations but does not specifically handle labor relations within the airline sector.
