The International Brotherhood of Teamsters, also known as the Teamsters Union, is a labor union in the United States and Canada.
The Teamsters are America’s largest, most diverse union. In 1903, the Teamsters started as a merger of the two leading team driver associations.
The Teamsters are known as the champion of freight drivers and warehouse workers, but have organized workers in virtually every occupation imaginable, both professional and non-professional, private sector and public sector.
