It is conventional wisdom that because of lucrative contracts negotiated by the United Auto Workers (UAW) under Walter Reuther's leadership, most autoworkers in the U.S. enjoyed steady work, increasing wages, and improved benefits in the postwar boom following World War II. In short, autoworkers entered the middle class. In contrast, this book argues that for Detroit autoworkers there was no postwar boom. Instead, the years from 1945 to 1960 were dominated by job instability and economic insecurity. This argument is based largely on oral history interviews and research in local newspapers, which covered the auto industry extensively. Conditions were worse for African Americans and white women, but almost all autoworkers experienced precarious, often dire circumstances. Recessions, automation, decentralization, and the collapse of independent automakers in Detroit are part of the story, but materials shortages, steel, coal, and copper strikes, parts supplier strikes, wildcat strikes, overproduction (especially in 1955), hot weather, cold weather, plant explosions, age, race, and gender workplace discrimination, and the inability of autoworkers to afford new cars contributed to instability and insecurity. Hardly anyone in the 1950s—whether ordinary autoworkers, union leaders, auto company executives, business analysts, or local shopkeepers—thought that the decade was marked by steady work, improving wages, or anything resembling predictable income for autoworkers.
