A more accurate title: "Some guy has opinions on what managers should do so we typed those opinions up."
My other big objection is that the pieces of advice (e.g. "manage up") seem stock and not actionable. Merely telling one to "manage up," (i.e. make your boss happy) is a new phrase for something entirely obvious. Nobody would disagree with "Make your boss happy," but somehow you spin the phrase in a new way and make a new lexicon around it and you have a facade of content.
