I would recommend Radical Candor to anyone that is a manager or has a manger. Kim Scott does a good job of prioritizing the need to treat everyone as a human being first-and-foremost and to "care personally" while "challenging directly". This is something that often gets lost in the corporate environment.

Scott presents a number of personal examples (sometimes repetitive and include name dropping) and realistic concrete practices that point toward a non-zero sum environment in which individuals and business can achieve great results.
