Teamsters Local 25 is a labor union local of the International Brotherhood of Teamsters headquartered in the Charlestown neighborhood of Boston, Massachusetts, that represents drivers, warehouse workers and other members across many employers in the region. Active for about a century, the local negotiates contracts and provides member benefits such as a 401K plan, credit union, pension fund, health coverage and scholarships, and runs organizing campaigns, training classes and community events. Sean O'Brien led the local before becoming general president of the Teamsters in 2022, and its members work for employers such as UPS and in freight, beverage and construction.
