of 1950 made provision for the health and safety of workers employed in factories "in which there is carried on the manufacture or decoration of pottery or certain allied manufactures or processes." Law Various law reforms were also carried out by Attlee's government. The Criminal Justice Act of 1948 provided for new methods to deal with offenders, and abolished hard labour, penal servitude, prison divisions and whipping. The Law Reform (Personal Injuries) Act 1948 enabled employees to sue their employers in cases where they experienced injury due to the negligence of a fellow employee. The Legal Aid and Advice Act of 1949 introduced a state aided scheme to assist those who couldn't afford legal services. Post-war consensus Most historians argue that the main domestic policies (except nationalisation of steel) reflected a broad bipartisan consensus. The post-war consensus is a historians' model of political agreement from 1945 to the late-1970s. In 1979 newly elected Prime Minister Margaret Thatcher rejected and reversed it. The concept claims there was a widespread consensus that covered support for coherent package of policies that were developed in the 1930s, promised during the Second World War, and enacted under Attlee. The policies dealt with a mixed economy, Keynesianism, and a broad welfare state. In recent years the validity of the interpretation has been debated by historians. The historians' model of the post-war consensus was most fully developed by Paul Addison. The basic argument is that in the 1930s, Liberal Party intellectuals led by John Maynard Keynes and William Beveridge developed a series of plans that became especially attractive as the wartime government promised a much better post-war Britain and saw the need to engage every sector of society. The coalition government during the war, headed by Churchill and Attlee, signed off on a series of white papers that promised Britain a much improved welfare state. After the war, the promises included the National Health Service, and expansion of education, housing, and a number of welfare programmes. It did not include the nationalisation of iron and steel, which was approved only by the Labour Party. The model states that from 1945 until the arrival of Thatcher in 1979, there was a broad multi-partisan national consensus on social and economic policy, especially regarding the welfare state, nationalised health services, educational reform, a mixed economy, government regulation, Keynesian macroeconomic policies, and full employment. Apart from the question of nationalisation of
