The NALC Bulletin provides the latest information on the status of key legislation, major arbitration decisions, and special activities of the union. During contract negotiations and/or contract arbitrations the Bulletin also provides the general membership with speedy and detailed information on bargaining and arbitration testimony, as well as the first compete data on a  new contract.

The Bulletin is published generally on a bi-weekly basis, although more or less frequently as needed. Approximately 13,000 copies of the Bulletin are mailed to branch officials and shop stewards for posting on NALC bulletin boards at postal stations.
