Introducing new technologies often crush unions; indeed, sometimes that is the purpose. However, the International Longshore & Warehouse Union (ILWU), on the US Pacific Coast, demonstrates that need not occur. In 1960, the ILWU and Pacific Maritime Association signed the Mechanization & Modernization agreement (M&M). M&M represented among the first efforts by a union to shape this process—to “get a share of the machine.” Although workers understood that new technologies cannot simply be resisted, tremendous controversy still existed, culminating in the US shipping industry’s longest strike ever. In 1971, members of the San Francisco Bay area’s Local 10 led this strike, having experienced containerization most extensively. Although their numbers plummeted, those remaining maintained power at a strategic point of the global economy. Looking at how these workers managed to survive and partially shape the introduction of a valuable new technology suggests that it, and globalization, need not always destroy unions.
