Low wages, long working hours, monotonous and dangerous work, and abusive supervisory practices led to high employee turnover, violent strikes, and the threat of social instability. Intellectually, industrial relations was formed at the end of the 19th century as a middle ground between classical economics and Marxism, with Sidney Webb and Beatrice Webb's Industrial Democracy (1897) being a key intellectual work. Industrial relations thus rejected the classical econ. Institutionally, industrial relations was founded by John R. Commons when he created the first academic industrial relations program at the University of Wisconsin in 1920. Another scholarly pioneer in industrial relations and labour research was Robert F. Hoxie. Early financial support for the field came from John D. Rockefeller Jr. who supported progressive labour–management relations in the aftermath of the bloody strike at a Rockefeller-owned coal mine in Colorado. In Britain, another progressive industrialist, Montague Burton, endowed chairs in industrial relations at the universities of Leeds, Cardiff, and Cambridge in 1929–1930. Beginning in the early 1930s there was a rapid increase in membership of trade unions in the United States, and with that came frequent and sometimes violent labour–management conflict. During the Second World War these were suppressed by the arbitration powers of the National War Labor Board. However, as the Second World War drew to a close and in anticipation of a renewal of labour–management conflict after the war, there was a wave of creations of new academic institutes and degree programs that sought to analyse such conflicts and the role of collective bargaining. The most known of these was the Cornell University School of Industrial and Labor Relations, founded in 1945. But counting various forms, there were over seventy-five others. These included the Yale Labor and Management Center, directed by E. Wight Bakke, which began in 1945. An influential industrial relations scholar in the 1940s and 1950s was Neil W. Chamberlain at Yale and Columbia universities. In the 1950s, industrial relations was formalized as a distinct academic discipline with the emergence in the UK of the so-called "Oxford school", including Allan Flanders, Hugh Clegg, and Alan Fox, Lord William McCarthy, Sir George Bain (all of whom taught at Nuffield College, Oxford), as well as Otto Kahn-Freund (Brasenose College, Oxford). Industrial relations was formed with a strong problem-solving orientation that rejected both the classical economists' laissez-faire solutions to labour problems and the Marxist solution of class revolution. It is this approach
