The International Workers of the World (IWW) is a labor union founded in 1905 in Chicago, Illinois. It aims to unite all workers, regardless of their trade or skill level, to promote social and economic justice. The IWW is known for its radical approach to labor rights, advocating for direct action and solidarity among workers. The IWW is often associated with the concept of industrial unionism, which seeks to organize workers across entire industries rather than by individual trades. The union has a rich history of activism, including involvement in various labor movements and strikes throughout the 20th century.
