Sutton also has two blogs, on which he's posting rousing, blood stirring commentary on the reception he's getting for the assholes book. One is "official" at Harvard Business Review: The Working Life. There's a pointer there to an online test you can take to determine if you are an asshole, and it includes gems I've posted about before, such as: “You are constantly buttering up your boss and other powerful people, and expect the same treatment from your underlings.”
His other is his personal blog, Work Matters, which has even more about the book's reception. If you're interested in asshole managers and hostile workplaces, they're both good reading.
Sadly, I suspect even assholes are passing these on -- consistent with the "Incompetent People Don't Know They're Incompetent" findings I've posted about before. And I fully understand the potentional implications of my pointing this out. :-)
