In 1889, a "Postmen's Union" was founded in Clerkenwell by Tom Dredge and John Lincoln Mahon. This dissolved after many of its members were sacked, but two years later, C. Churchfield established the "Postmen's Federation" as a more cautious organisation. It immediately recruited 3,721 members, and survived, offering welfare benefits to members from 1895 and publishing The Postmen's Gazette.
In 1912, George Harold Stuart was elected as general secretary; Duncan Campbell-Smith describes him as the "single most impressive officer among all the postal union staffs". Under his leadership, the union began admitting women. It negotiated a merger with the Fawcett Association and the Postal and Telegraph Clerks' Association in 1919, forming the Union of Post Office Workers.
