On this day in 1976, a small group of courageous Teamsters met in Kent, Ohio, to form Teamsters for a Democratic Union (TDU).

At the time of TDU's founding, the IBT General Executive Board and many local unions were dominated by organized crime. Contracts could be imposed even if the majority voted against them. Members who spoke up could be met with violent intimidation.

Teamster General President (and FBI informant) Jackie Presser organized the Brotherhood of Loyal Americans and Strong Teamsters (BLAST) goon squad to attack TDU meetings and the founding Convention. Presser announced at the 1986 Teamster Convention that "Today you've just witnessed the funeral of TDU." The following year, he was indicted for racketeering—and TDU kept growing.

TDU has since become the longest-lasting and largest reform movement in U.S. labor history. TDU members led campaigns to secure crucial democratic rights and win improvements in wages, benefits and working conditions for hundreds of thousands of workers.

TDU is an inspiration for rank-and-file movements throughout the country who are fighting to rebuild the labor movement.

The struggle continues. Last year, we formed a coalition to back Teamsters United and nearly won the closest election in Teamster history. There is a lot more history still to be made.
