Once again. Here's the connection. Work psychology involves occ stress, occupational health, improving workers wellbeing through strategies/interventions, and work safety. in fact work psychology covers everything OHP says it covers and all the the things that OHP say they do. References already provided above 5 or 6 of them I think. If more are needed, they can be provided. Given Occupational health psych is a specialization of health psych, it is logical that that work psych and health psych particularly its specialization occupatiional health psych. Your thought?
