Book review: "Finally, Dr. Dale Masi has written a comprehensive book that addresses a critical deficiency in the Employee Assistance (EA) knowledge base—the need for a definitive and evidential resource that documents the history and evolution of Employee Assistance Programs (EAP) in the United States (U.S.) from the early beginnings through 2020. This book details a chronologically accurate and authoritative narrative that begins with early antecedents of EAP and concludes with future directions for the field."
