"The book is a welcome addition to the growing literature on white collar groups.... The presentation is noteworthy because it takes several new directions. [The] book departs from the traditional analysis of white collar employees. They are not treated en masse or as belonging to at most a few discrete but homogeneous segments. Instead, the book focuses on three industries: banking, electrical manufacturing, and public welfare. ... By selecting particular industries as the unit of analysis, McColloch can examine white collar occupations in minute detail. The picture that emerges is by no means uniform, but shows richness and variability in job content. ... [It is] a valuable contribution to our understanding of white collar classes."-Business History Review
