Abstract
Worker health and safety training is an important part of occupational health and safety programs. In the United States, governments, unions, employers, university programs, and health and safety advocacy organizations make training available. This article considers training effectiveness research conducted and supported by the National Institute for Occupational Safety and Health (NIOSH), and some done in collaboration with the Institute for Work and Health (Canada). Differing perspectives regarding the purpose of worker health and safety training are reviewed and critiqued. We assert that a focus on changing the working behaviors of workers exposed to hazardous conditions is less appropriate and scientifically rigorous than a focus on helping workers establish the power to reduce and eliminate workplace hazards. For training to lead to a decrease in morbidities and fatalities related to hazardous exposures, it needs to be integrated with workers' attainment of such power.
