Technology has sped up the world of retail clothing, rushing affordable, trendy garments to consumers and enriching multinational retail giants like Zara and H&M. But beneath the success of fast fashion, there is a grimmer story to be told—that of the people who do the actual producing and selling. Working undercover in two of the world’s largest fast fashion stores in New York City, Madison Van Oort observed firsthand how data and surveillance shape the lives of low-status workers in an industry in flux—and how these workers are fighting back. Worn Out provides an on-the-ground look at how technology helps create this just-in-time workforce, how feminized and racialized workers experience and respond to new forms of digital control, and how collective struggles for racial, gender, and economic justice in and around retail spaces inform these workers’ resistance. ‘Worn Out’ draws on interviews with dozens of front-line workers and labor activists, and on evidence gathered at corporate conferences, to expose the exploitative reality of retail labor in the digital age. Van Oort shows how digital tools lubricate the shift toward just-in-time retail by collecting real-time data on not only customer behavior but also worker performance and how these tools—including automated scheduling platforms, biometric timeclocks, and cashier metrics—increase these workers’ already heightened insecurity. One of the first ethnographies of this “thriving” industry, Van Oort’s book pulls open the curtain between production and consumption and reveals the real cost of fast fashion.
