Joseph Maddison (born 1838) was a British trade unionist.
[1][2] Maddison supported the formation of the General Federation of Trade Unions and served as its first treasurer.
He also supported the Labour Representation Committee, and backed his old friend Arthur Henderson as the union's first sponsored Parliamentary candidate.
[1][2] In 1902, Maddison visited the United States to study foundry working methods there.
The tour was sponsored by A. Mosely, who later proposed a Civic Federation Scheme of compulsory negotiations, which Maddison backed, but the union as a whole rejected.
