The Transport Workers Union (TWU) is a labor union in the United States that represents workers in the transportation sector. Founded in 1934, it advocates for the rights and interests of its members, including those in the airline, bus, and rail industries. The union negotiates contracts, provides support during disputes, and works to improve working conditions and wages. The TWU is affiliated with the AFL-CIO, a larger federation of labor unions. It plays a crucial role in organizing workers and ensuring they have a collective voice in negotiations with employers. The union also engages in political advocacy to influence policies affecting transportation workers.
