This book is composed of twelve lessons that can be taught as a supervisor's class so when they have completed all the lessons, they will be an effective supervisor. Each lesson is designed so the participant reads the information, is given an opportunity to discuss the material, and then answers questions at the end of each lesson that facilitates discussion to enhance the learning opportunity. The lessons are based on real-life situations that a supervisor encounters every day on the job with no theory, just straight-to-the-point information that the reader can understand and put into practice on their job.
