Born in Liverpool, Stanley grew up in Salford. He worked in a foundry and joined the United Society of Boilermakers and Iron and Steel Shipbuilders. In 1922, he transferred to the British Iron, Steel and Kindred Trades Association (BISAKTA), and was elected as secretary of its Manchester branch the following year.

Stanley succeeded House as its general secretary in 1939.
