Denise Kasparian’s Co-operative Struggles provides an in-depth study of two worker co-operatives in the Buenos Aires area today to reveal how co-operatives emerge, are governed, and disappear. She successfully confronts people’s implicit assumptions about co-operatives with observations from everyday realities of working in Argentinian worker co-operatives in the 2000s and 2010s. Her research thereby puts several dominant myths about the co-operative economy into perspective. During these decades, there was a boom in worker co-operatives in Argentina thanks to a combination of successful workers’ struggles and new co-operative-friendly legislation. Her first example is a hotel company that went bankrupt and was subsequently recuperated by workers and adapted into a co-operative business. Through the sustained occupation of the hotel, workers took possession of the building as a recuperated business, but afterward, a difficult process commenced of reconciling the financial and social tensions involved in managing a profitable yet self-managing co-operative. Her second case study is an unemployed workers’ organization in a poor and environmentally degraded neighborhood in the greater Buenos Aires area. Through the Argentina Works Program, the municipal government and social organizations collaborated with local unemployed women to form a worker co-operative that focuses on local improvement works, like cleaning up the polluted river that flows through the neighborhood.
