Book excerpt: The extent of mental illness concerns in the workforce is becoming increasingly apparent. Stress, depression, anxiety, workplace bullying and other issues are costing businesses billions every year in lost productivity, poor treatments and employee retention. Unless appropriately addressed, issues related to mental illness difficulties will result in stiff financial, organizational, and human costs for organizations. Drawing on empirical evidence from North America, the United Kingdom, Australia and New Zealand, the book provides a practical guide to identifying, understanding, treating and preventing individual and organizational mental health issues. The authors illustrate how organizations can save money and improve the health and wellbeing of their employees by using a psychological disability management approach in the treatment and accommodation of mental illness issues. This book will meet the needs of human resources professionals, administrators of employee assistance programs, industrial and organizational psychologists, mental health practitioners, those teaching or studying psychology and disability management, and more generally will serve to enlighten students of business management and practicing managers regarding a major workforce risk factor.
