The centerpiece of this sociological study of "emotional labor," or how businesses profit off employee feelings, is a look at flight attendants and debt collectors, the flight attendants being extracted of cheer and the debt collectors being extracted of aggression. That's the most interesting part of the book, and it's unfortunately also very small. I suppose the theories of the way feeling acts as a form of currency in our personal lives are interesting too, but that's just supposed to be the preamble to the meat, which you end the book wishing there was much more of. Although that could be a function of the book's conclusions no longer really being all that surprising (corporate emotional extraction=bad), that is, at least for older folks—the "fake it 'til you make it" and "hustle culture" generation was apparently oblivious to everything that was in here; businesses needed to extract human resources and these people just sort of fought to be the first in line, tearing open their own veins. And now YouTube hides "burnout" videos, and these people are our bosses. Three stars.
