Total Worker Health


Taking a Total Worker Health® approach can help your organization create and sustain a culture that supports overall worker well-being.

What Is Total Worker Health®?

Total Worker Health® (TWH) is defined as policies, programs, and practices that integrate protection from work-related safety and health hazards with promotion of injury and illness-prevention efforts to advance worker well-being.  It is a holistic, organization-wide approach to worker well-being. As stated by NIOSH, “The Total Worker Health® (TWH) approach prioritizes a hazard-free work environment for all workers” and recognizes ". . . that work is a social determinant of health."

Understanding and applying TWH principles can help your organization move from a compliance focus to a risk-based approach to safety management. These principles help you consider not only the physical work environment, but also the physical and psychosocial work environment and their impact on workers. The resources provided here will help you better understand and use a TWH approach to prevent injuries and illnesses in your organization while also improving overall worker well-being.
