that underlies the New Deal legislation in the United States, such as the National Labor Relations Act and the Fair Labor Standards Act. By the early 21st century, the academic field of industrial relations was often described as being in crisis. In academia, its traditional positions are threatened on one side by the dominance of mainstream economics and organizational behaviour, and on the other by postmodernism. In policy-making circles, the industrial relations emphasis on institutional intervention is trumped by a neoliberal emphasis on the laissez-faire promotion of free markets. In practice, trade unions are declining and fewer companies have industrial relations functions. The number of academic programs in industrial relations is therefore shrinking, while fields such as human resource management and organizational behaviour grow. The importance of this work, however, is stronger than ever, and the lessons of industrial relations remain vital. The challenge for industrial relations is to re-establish these connections with the broader academic, policy, and business worlds. Theoretical perspectives Industrial relations scholars such as Alan Fox have described three major theoretical perspectives or frameworks, that contrast in their understanding and analysis of workplace relations. The three views are generally known as unitarism, pluralism, and the radical or critical school. Each offers a particular perception of workplace relations and will, therefore, interpret such events as workplace conflict, the role of unions and job regulation differently. The perspective of the critical school is sometimes referred to as the conflict model, although this is somewhat ambiguous, as pluralism also tends to see conflict as inherent in workplaces. Radical theories are strongly identified with Marxist theories, although they are not limited to these. Pluralist perspective In pluralism, the organization is perceived as being made up of divergent sub-groups, each with its own legitimate interests and loyalties and with their own set of objectives and leaders. In particular, the two predominant sub-groups in the pluralist perspective are the management and trade unions. The pluralist perspective also supports that conflict is inherent in dealing with industrial relations since different sub-groups have different opinions in the day-to-day operations. Consequently, the role of management would lean less towards enforcing and controlling and more toward persuasion and coordination. Trade unions are deemed legitimate representatives of employees, conflict is resolved through collective bargaining and is viewed not necessarily as a bad thing and, if managed, could, in fact, be channeled towards evolution and positive change.
