**5. Conclusions**

PUSH is an online training program utilizing a Total Worker Health® approach to address occupational safety and health for younger workers [12]. These results suggest the usefulness of online-training to improve the safety, health and well-being of young workers, which prepares them to better prevent workplace hazards. Due to its inclusion of comprehensive topics on health and safety and its acceptance by young workers in diverse work environments, the PUSH training could be expanded to young workers in other industries to increase their awareness on workplace rights and responsibility, health communication in order to promote health and safety, and improve well-being.
