This book is a 3.5 star for me. The chapters are easy to read. It's nice that they keep repeating concepts in different applicable ways. The questions they provide managers to think about and ask are helpful. The examples and anecdotes are also helpful. For those who have never managed people, been in HR or had people indirectly reporting to them, this is a good book to read.
For those who have managed before and are running into issues, this is a good book to provide refresher tips. In addition, it helps to provide proactive steps to keep your star players. What I liked is that in this book, it doesn't say to keep everyone. It's really to keep the ones who have potential, deliver and those that are engaged. Maintaining the status quo is not a message this book preaches. The takeaways are: listen, engage, have fun, don't be a jerk and understand their motivations. Basically, money doesn't solve everything and a bad boss is a top reason why people leave. I concur as I moved on when I had a bad boss.
