Term International Brotherhood of Teamsters Definition: One of the largest labor unions in the United States, this was established in 1903 and represents truck drivers, chauffeurs, warehouse workers, and labor in related activities. Their name was taken from the teamsters of the 1800s who guided wagons pulled by teams of horses or other animals. Their modern day counterparts have replaced teams of horses with diesel engines, but their function remains much the same. The Teamsters Union was originally part of the AFL-CIO, but was expelled in 1957 due to corruption among union leaders. The Teamsters Union rejoined the AFL-CIO in 1987.
