Temp: How American Work, American Business, and the American Dream Became Temporary tries to tell two stories: that of the rise of temp labor, and another, of the large management consulting companies. It does a great job of describing both the life of temps and how they became so ubiquitous, through the recommendations of consulting companies. One the other hand, the detailed history of consulting companies, and the lifestyle of consultants and partners, seems pretty irrelevant and even distracting.
Perhaps the most interesting part of the book is showing that current labor laws are specifically poorly-designed for temps (or, said another way, the temp status was specifically designed to get around labor laws!) It would be important for politicians to understand that there are many of us without a regular paycheck, but we are forced to play by rules defined around so-called wage slaves.
