The health risks and challenges facing today’s workers and employers are significantly different than when the Occupational Safety and Health Act of 1970 was signed into law. Today’s workers face not only the traditional risks of chemical, physical, and biological hazards but also increased risks related to the changing nature of work, shifting workforce demographics and diversity, evolving employment patterns, and the changing workplace environment.

Building on four decades of scientific knowledge to prevent worker injury and illness and as an active part of the National Occupational Research Agenda (NORA) priority areas, NIOSH’s Total Worker Health®  Program supports ground-breaking research that addresses the implications of today’s changing workplace and responds to demands for information and practical solutions to the health, safety, and well-being challenges that workers face. 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. This approach prioritizes a hazard-free work environment for all workers and comprehensively integrates workplace systems relevant to the control of hazards and exposures, organization of work, compensation and benefits, work-life integration/management, and organizational change management.


The purpose is to support Centers of Excellence for Total Worker Health® to advance the overall safety, health, and well-being of the diverse population of workers in our nation. Centers accomplish this through multidisciplinary research, intervention, outreach and education, and evaluation activities.
