Every year, many millions of working days are lost as a result of ill health. Drawing upon research evidence, this text identifies the factors which contribute to ill-health at work, and looks at what organizations can do to promote and maintain a healthy workforce. The authors, who are two of the most established names in the field of occupational health psychology, examine both individual factors, such as lifestyle, personality and emotional intelligence, and specific workplace issues, such as bullying, harassment, and work-life balance. They discuss strategies for promoting and maintaining health, including organizational policies, auditing and monitoring health, and designing and evaluating strategies for improvement: and they consider the health issues emerging from new forms of working, such as call centres, home working and virtual teams.
