As others have noted Peopleware is a good book as is Slack by the same author. Slack will likely conflict with the philosophy of PMP focused organizations but it's very relevant. I strongly discourage relying on the many popular management books like "5 dysfunctions of a team". Sorry the all knowing CEO doesn't exist and as a manager, you won't know all the answers either. Personally, books focused on team empowerment, e.g., books on scrum, The Toyota Way, etc. are probably more helpful. Management, as far too few recognize, is about team empowerment and staff development. It's not about you and being the boss.
