Industrial relations or employment relations is the multidisciplinary academic field that studies the employment relationship; that is, the complex interrelations between employers and employees, labor/trade unions, employer organizations, and the state. The newer name, "Employment Relations" is increasingly taking precedence because "industrial relations" is often seen to have relatively narrow connotations. Nevertheless, industrial relations has frequently been concerned with employment relationships in the broadest sense, including "non-industrial" employment relationships. This is sometimes seen as paralleling a trend in the separate but related discipline of human resource management. While some scholars regard or treat industrial/employment relations as synonymous with employee relations and labour relations, this is controversial, because of the narrower focus of employee/labour relations, i.e. on employees or labour, from the perspective of employers, managers and/or officials. In addition, employee relations is often perceived as dealing only with non-unionized workers, whereas labour relations is seen as dealing with organized labour, i.e unionized workers. Some academics, universities and other institutions regard human resource management as synonymous with one or more of the above disciplines, although this too is controversial. Overview Industrial relations examines various employment situations, not just ones with a unionized workforce. However, according to Bruce E. Kaufman, "To a large degree, most scholars regard trade unionism, collective bargaining and labour–management relations, and the national labour policy and labour law within which they are embedded, as the core subjects of the field." Initiated in the United States at end of the 19th century, it took off as a field in conjunction with the New Deal. However, it is generally regarded as a separate field of study only in English-speaking countries, having no direct equivalent in continental Europe. In recent times, industrial relations has been in decline as a field, in correlation with the decline in importance of trade unions and also with the increasing preference of business schools for the human resource management paradigm. Industrial relations has three faces: science building, problem solving, and ethical. In the science building phase, industrial relations is part of the social sciences, and it seeks to understand the employment relationship and its institutions through high-quality, rigorous research. In this vein, industrial relations scholarship intersects with scholarship in labour economics, industrial sociology, labour and social history, human resource management, political science, law, and other areas. Industrial relations scholarship assumes that labour markets are not perfectly competitive and thus, in contrast to mainstream economic theory, employers
