Productivity was a more serious problem. Lack of maintenance and capital investment during the war, antiquated machinery, the understandable physical weariness of a labor force that had been working at top speed since 1939 all contributed to a relatively low rate of output per man year in industry compared with the United States. In 1948 the Labor government took an important step to meet the problem when it formed the Anglo-American Productivity Council. Its goal was to increase productivity in Britain through study of manufacturing methods in the United States. Teams representing management, technicians, and shop workers went to the United States to study American methods. They returned to boost British productivity. The effort did not stop there. An independent body, the British Productivity Council, was established in 1952 to continue the work. Represented on it are the British Employers' Confederation, the Federation of British Industries, the Trades Union Congress, the Association of British Chambers of Commerce, the National Union of Manufacturers, and the nationalized industries. Under the aegis of the Council, Local Productivity Committees have been formed and the exchange of information and visits between groups from industrial firms have been encouraged. The Council is a good example of the British approach to a national problem in modern times. The nation's difficulties have gradually, but not entirely, eased the old enmities between some employers and workers. Aware of the extreme seriousness of the situation, they are working together to boost productivity, and they are making headway. Employer-worker consultation is becoming the rule. When the rule is broken by either side there is trouble. The increase in productivity has been steady. Taking 1948 as the base year with a figure of 100, output per man year in industry rose to 105 in 1949. Save for 1952, when there was a slight relapse, the figure has improved steadily ever since. Production has shown a corresponding rise. The general index of industrial production, using 1948 as the base year of 100, rose from 114 in 1952 to 121 in 1953 and then jumped to 136 for 1955. But production leveled off in 1956. As that year ended, the expectation was that 1957 would see a new rise in production as the capital investment of the previous five years began to show results.
