National Union of Distributive and Allied Workers
The union was founded in 1921, when the Amalgamated Union of Co-operative Employees merged with the National Union of Warehouse and General Workers. The Co-operative Insurance Staff union split in 1922, but several small unions joined during the 1920s, and membership reached 96,000 by 1926, rising to 274,000 in 1946. By this point, four-tenths of its members were women.
In 1947, NUDAW merged with the National Amalgamated Union of Shop Assistants, to form the Union of Shop, Distributive and Allied Workers. Joseph Hallsworth was General Secretary of the union for its entire existence.
