I'm not a manager, but half of the essays in Managing Humans are aimed at understanding what's going on with your manager. Which I suppose makes sense, even if you are a manager, because unless you're the CEO even managers have managers. It's also aimed at the Software Engineering world, and even just being in IT there were a few chapters that I kinda raced through as not-useful-here. It's all written in a light, breezy style (much as Lopp's blog Rands in Repose) and I think I've got some useful info.
