We welcome you to the NMB Help Desk. The mission of the National Mediation Board (NMB) is to minimize work stoppages by facilitating harmonious labor relations for airlines and railroads engaged in interstate commerce or travel within the United States pursuant to the Railway Labor Act (RLA). The Help Desk is the best NMB source of information regarding a broad range of employment and labor relations issues, particularly information about the RLA.

You are encouraged to use the Help Desk online, because it is heavily loaded with links internal to the Help Desk and external to the NMB and other web sites. Improving the Help Desk will be an on-going effort. Please note that calling or writing the NMB will not yield different answers. The Help Desk does not provide legal advice of any kind; see our full disclaimer.
