Excellent advice. Being brief means choosing the right words and closing the loop. I'd love to get a copy of the book and write a review!

I recommend "It's Okay to be the Boss," by Bruce Tulgan, to all my colleagues. It gives step-by-step directions with rationales for being a better leader and heading off problems early. Being a leader is hands-on and this book describes exactly why under-management is a problem in the workplace.
