Book Description: All firms wrestle with restructuring, involving consolidation of mergers and acquisitions on the one hand, and fragmentation through outsourcing and spin-offs on the other. Through an in-depth investigation into the organizational strategies of Japanese corporate management and union leaders in Japan, Mari Sako explores the issue of "organizational boundaries" that arises from such restructuring. Examining the strategy and structure of both businesses and trade unions, the book draws upon empirical evidence drawn from interviews conducted at Toyota and Matsushita and their respective unions. It examines their respective strategies in coping with organizational boundaries against the backdrop of changing labour markets, and, in the process, challenges widely held notions about Japanese corporate and union structures. Mari Sako goes on to explore the implications of these relationships in other advanced industrial countries for corporate restructuring, jobs, and labor market flexibility.
