Two major developments have occurred in recent years in the area of labor-management relations, both of them based on the principle of cooperation, in contrast with the traditional adversarial stance of the two parties. The first is cooperation between management and its counterpart in the labor movement, union leadership; and the second is cooperation between management and, with the approval of union leadership, employees considered as individuals or members of small work groups. If a single word is to serve as the slogan of labor-management cooperation, it well could be the word "communication." Labor-management cooperation is increasingly on the agenda of the country's largest corporations and unions. Like any new idea, the concept of employee participation in making work life more meaningful and the company more prosperous will necessarily involve a long evolutionary period in business and industry. At the level of everyday practicality, probably the most vital aspect of the programs is intensive preliminary training--in advance of the installation of a program--that would involve the proper techniques of cooperation and communication for the benefit of every person in the corporation.
