Teamsters for a Democratic Union (TDU) is the united rank and file movement to reform the International Brotherhood of Teamsters (IBT), or Teamsters Union. TDU was created out of the merger of the Professional Drivers Council (PROD) and TDU in 1980. TDU is a grassroots organization with chapters from coast to coast in the USA and Canada, and believes in returning the Teamsters to its membership.
