History of labour law in the United Kingdom concerns the development of UK labour law. Before the Industrial Revolution and the introduction of mechanised manufacture, regulation of workplace relations was based on status, rather than contract or mediation through a system of trade unions. Serfdom was the prevailing status of the mass of people, except where artisans in towns could gain a measure of self regulation through guilds. In 1740 save for the fly-shuttle the loom was as it had been since weaving had begun. The law of the land was, under the Act of Apprentices 1563, that wages in each district should be assessed by Justices of the Peace. From the middle of the 19th century, through Acts such as the Master and Servant Act 1867 and the Employer and Workman Act 1875, there became growing recognition that greater protection was needed to promote the health and safety of workers, as well as preventing unfair practices in wage contracts.
