After the New Ministries and Secretaries Act 1916 the Ministry of Labour took over Board of Trade responsibilities for conciliation, labour exchanges, labour and industrial relations and employment related statistics. Following the First World War it supervised the demobilisation and resettlement of ex-servicemen. In the 1920s it took over all Board of Education work relating to youth employment and responsibility for training and employment of the disabled from the Ministry of Pensions. It also supervised trade union regulations. Under the Trade Boards Act 1918 the Ministry enforced the minimum wage, helped establish joint industrial councils, and set up the Industrial Court in 1919 for arbitration of industrial disputes. It proposed multiple Unemployment Insurance Acts amendments, administered benefits through employment exchanges, employed the unemployed through special works schemes. From 1939, the department was renamed the Ministry of Labour and National Service, reflecting new duties under the National Service Act 1939. It allocated people to work between the armed forces, civil defence and industry, and to administer the Schedule of Reserved Occupations. The National Joint Advisory Council, comprising employers' and workers' representatives, was consulted. From 1941, one Deputy Secretary for the Ministry controlled peacetime work, and another coordinated work on manpower statistics, intelligence, armed forces recruitment, civilian war work and training and labour supply. In April 1945, functions relating to unemployment insurance and assistance were transferred to the Ministry of National Insurance, but the Ministry of Labour retained responsibility for employment exchanges. In June 1945, the Board of Trade was handed responsibility for industrial policy, except that concerning labour power. At the end of the War, the National Service Department wing was wound up and its functions passed to the Military Recruitment Department. In 1947 the ministry introduced the Control of Engagement Order, 1947, which limited the rights of workers to leave various industries, and gave labour exchanges the right to direct the unemployed to specific jobs. In 1959 the department became the Ministry of Labour once more. It was renamed the Department of Employment and Productivity in 1968, and became the Department for Employment in 1970.
