Closing Sysco presents a history of deindustrialization and working-class resistance in the Cape Breton steel industry between 1945 and 2001. The Sydney Steel Works is at the heart of this story, having existed in tandem with Cape Breton’s larger coal operations since the early twentieth century. The book explores the multifaceted nature of deindustrialization; the internal politics of the steelworkers’ union; the successful efforts to nationalize the mill in 1967; the years in transition under public ownership; and the confrontations over health, safety, and environmental degradation in the 1990s and 2000s. Closing Sysco moves beyond the moment of closure to trace the cultural, historical, and political ramifications of deindustrialization that continue to play out in post-industrial Cape Breton Island. A significant intervention into the international literature on deindustrialization, this study pushes scholarship beyond the bounds of political economy and cultural change to begin tackling issues of bodily health, environment, and historical memory in post-industrial places. The experiences of the men and women who were displaced by the decline and closure of Sydney Steel are central to this book. Featuring interviews with former steelworkers, office employees, managers, politicians, and community activists, these one-on-one conversations reveal both the human cost of industrial closure and the lingering after-effects of deindustrialization.
