Arthur Moyle, Baron Moyle, CBE (25 September 1894 – 23 December 1974) was a British bricklayer, trade union official and politician. As a member of parliament for nineteen years, he was principally known for serving as Parliamentary Private Secretary to Clement Attlee during Attlee's Premiership. He was also perennially lucky in the ballot for Private Member's Bills.
Moyle was a native of Cornwall, the son of a stonemason. He grew up in Llanidloes, Montgomeryshire and went to the National School there. He learned the trade of a bricklayer, and worked in Wales and the Welsh Marches. He was active in trade union work and in 1918, he became Secretary of the Shrewsbury Building Trades Federation.
From 1920 Moyle was promoted to be an official of the National Federation of Building Trade Operatives. He also became active in the Labour Party, and in the 1924 general election he was chosen as Labour Party candidate for Torquay. Moyle's intervention in what was a close fight between the Conservatives and Liberals, where Labour had not fought in the two previous elections, was met with annoyance on the part of the Liberal Party. In the end, the Liberals lost the seat by much more than the 2,752 votes which Moyle obtained.
After trade union mergers, Moyle became National Officer of the National Union of Public Employees, which made him responsible for local authority workers generally and not just those in construction. In the year 1937–38 Moyle was Chairman of the National Joint Council for Local Authorities Non-Trading Services. He was a spokesman of a delegation to the government to ask for pensions for manual workers as well as local government officers in 1937.
In May 1938 he joined a delegation pressing for a Whitley Council for nurses, to fix minimum salaries and maximum hours. During the Second World War, Moyle served on a departmental committee on Nurses' salaries under Lord Rushcliffe. Moyle was a member of the National Joint Council for Local Authorities Administrative Professional, Technical and Clerical Staffs, and in 1945 was chairman of the Trade Union Congress Local Advisory Committee.
