[Excerpt] Traditionally, unions have exercised their economic power through the strike and the boycott to gain collective bargaining agreements and through the day-to-day enforcement of contract provisions. But the rapidly growing mobility of capital and the increased rate of introducing new technologies have increasingly neutralized the effectiveness of labor's fundamental tools.

Thus, it is crucial that unions begin to develop new tools to enhance the economic power of workers. This means that labor must redefine its role with respect to the economy and to the process of allocating resources in the society. Increasingly, unions are demanding plant closing protections, a voice in the introduction of new technologies, restrictions on subcontracting, commitments for reinvestment in existing facilities, and job security for current workers.
