This study of available evidence on cooperative union-management efforts to solve employment problems indicates that roughly one-half of the larger unionized manufacturing facilities have embarked on cooperative efforts. Thus, larger firms have already made the decision to cooperate or not, and targeting government money to them to encourage cooperation would not be beneficial. The limited available evidence suggests that government assistance could make a difference by helping smaller organizations decide to cooperate and by helping them in the initial implementation of cooperative efforts. Few cooperative efforts enlist or encompass a majority of employees. The key to the success and longevity of cooperative efforts is finding mechanisms or processes by which the parties can juxtapose relative power activities and cooperative activities. The overriding policy implication is that any government assistance should be focused on helping private parties make the transition from experimentation to institutionalization. The Department of Labor should commit $500,000 to support rigorous studies and coordinate dissemination of their findings through the Bureau of Labor and Management Relations. The findings can be further disseminated through seminars and more effective use of areawide labor-management committees. (The document contains 2 figures, 5 tables, and 84 references.) (CML)
