The Trade Boards Act 1909 was a piece of social legislation passed in the United Kingdom in 1909. It provided for the creation of boards which could set minimum wage criteria that were legally enforceable. It was expanded and updated in the Trade Boards Act 1918. The main provision was to set minimum wages in certain trades with historically low wages, often due to a surplus of available workers due to the widespread employment of workers or lack of skills needed for employment.
