The Process and General Workers' Union was a British trade union representing workers involved in mining and processing salt, and related industries, mostly in Cheshire.
The union was founded in November 1888, as the Northwich Amalgamated Society of Salt Workers, Rock Salt Miners, Alkali Workers, Mechanics and General Labourers.
Six months later, William Yarwood took over as its general secretary, resolving numerous industrial disputes.

Three years later, it merged into the Transport and General Workers' Union.
