Employee health and well-being is important for employees, their families, the organizations they work for, and society as a whole. In the UK alone, over 11 million days are lost at work a year because of stress at work and it is clear that stress can cause a significant burden to both the individual and to wider society. Employers have a legal duty to protect employees from stress at work and should provide ways for their employees to prevent and cope with stress within the workplace. The association between work-related stress and poorer physical and mental health and well-being is well established, as well as work-stress related heart disease and mental health problems and societal costs caused by associated presenteeism and absenteeism, that can amount to 36%. The development of effective interventions to reduce work-related stress is, therefore, a major public health priority.
