The spectrum of documented stress-related problems among employees is extensive, ranging from psychological symptoms, including depression, anxiety, and somatic complaints to substance abuse and physical health problems such as heart disease, hypertension, and obesity.  These problems are costly to employers, employees and their families and society at large.  It is estimated that in the workplace, billions of dollars are lost each year in diminished productivity, high rates of absenteeism, and reduced performance resulting from these types of stress-related problems.
