Does unionization and working under collective agreements promote health?

This article focuses on the influence of unionization and collective agreements (CAs) on the social determinants of health (SDOH) and health outcomes in wealthy western nations, with a particular emphasis on Canada. It presents evidence that higher union density (UD) and collective agreement coverage (CAC) are associated with lower income inequality, fewer low-wage workers, and better health indicators such as reduced infant mortality and low birthweight rates. The article highlights that union membership and working under CAs improve wages, benefits, job security, and working conditions, which in turn positively affect health. Despite this, Canadian health promoters largely overlook the role of unions and CAs in health promotion, possibly due to political sensitivities and corporate influence. The authors argue for greater engagement between health promoters and the labour movement to address these gaps and promote health equity.
