This book presents a systematic case study of the hi-tech communications industry that reveals many trends in managerial authority in the workpace. Vallas reveals the mechanisms that enable advanced capitalist firms to achieve and maintain control over the workers they employ. He demonstrates that the spread and integration of automated technologies place lower level human labor in positions of declining power. The new regime does not deskill workers and need not lead toward what some have called electronic sweatshops. Nevertheless, Vallas concludes that increasing managerial control over production poses a major challenge to those who advocate labor participation in the management of American industries.
