This is an interesting study of institutions and labor relations in Brazil's most important industrial region during a period of impressive industrial growth and productivity improvement. The book's strengths derive from archival research on the internal workings of labor relations at the firm and industry-wide levels. Paying attention to the details of the work-place environment, Colistete argues that labor-training schemes, the organization of work, and factory environments each influenced industrial productivity in São Paulo during the postwar years.
