Bill Bayliss

William Bayliss (19 December 1886 – 12 February 1963) was a British trade unionist.

Born in Leicestershire, Bayliss left school at the age of twelve to work at a colliery. He joined the Leicestershire Miners' Association, but after becoming involved in industrial action, he was sacked and, a year later, moved to Nottinghamshire to find work. There, he became active in the Nottinghamshire Miners' Association, and also in the Labour Party.

Bayliss became his union branch delegate in 1915, and served a year as vice-president of the union in 1927, and a year as president in 1929. In 1932, he became the union's full-time financial secretary. whereupon he became an agent for the merged Nottinghamshire Miners' Federated Union (NMFU).

In 1943, Bayliss was chosen as one of the Trades Union Congress' two representatives to the American Federation of Labour.
