Traditional occupational safety and health protection programs have primarily focused on ensuring that work is safe and that workers are protected from the harms that arise from work itself.[1] Total Worker Health (TWH) builds on this approach through the recognition that work is a social determinant of health.[3] Job-related factors such as wages, hours of work, workload and stress levels, interactions with coworkers, and access to leave and healthful workplaces all can have an important impact on the well-being of workers, their families, and their communities.
