David Ranney's vivid memoir describes his work experiences between 1976 and 1982 in the factories of southeast Chicago and northwest Indiana, one of the heaviest industrial concentrations in the world. The author takes the reader on a walk through the heart of Chicago's South Side, observing the noise, heavy traffic, the 24-hour restaurants and bars, the rich diversity of people on the streets at all hours of the day and night, and the smell of the highly polluted air. Factory life includes stints at a machine shop, a shortening factory, a railroad car factory, a structural steel shop, a box factory, a chemical plant, and a paper cup factory. Along the way there is a wildcat strike, an immigration raid, shop-floor actions protesting supervisor abuses, serious injuries, a failed effort to unionise, and a murder.
