Book excerpt: This handbook is the practical guide to becoming a great manager. It covers all the major topics including hiring, coaching, feedback, one-on-ones, and decision making. It also covers some of softer, but equally important, topics like conflict resolution and mental health. Great management changes lives. In fact, it's one of the most single overlooked pieces of leverage in the world. Great managers are remembered like great teachers, inspirations who help others soar. That's why it's such a shame management training is so often overlooked. Successful individual-contributors are rewarded with a 'promotion' into management and then, more often than not, left to sink or swim. If you're a new manager, this book will shine a friendly light on the road ahead. And if you're an old dog, perhaps it'll teach you a trick or two. This handbook was written by Alex MacCaw and stress-tested at a company called Clearbit.
