In 1896, Chambers was elected as the Secretary of the International Transport Workers Federation,[2] serving until 1904.[3] He was active in the Independent Labour Party and was elected as the first General Secretary of the Workers' Union in 1898.[4] In 1909, he toured the ports of the United States with Havelock Wilson in order to increase trade union membership. He was then centrally involved in the seamen's strike of 1911.
