Injunctive safety norms, young worker risk-taking behaviors, and workplace injuries.

•We investigate how six sources of injunctive safety norms (ISNs) influence work risk-taking behavior and injuries•Parents’, supervisors’, and co-workers’ ISNs are associated with fewer work injuries via less frequent work risk-taking•Friends’ ISNs are associated with more frequent work injuries via more frequent work risk-taking•Young workers’ risk-taking is statistically associated with fewer work-related injuries•The six ISNs explained 5.2% of the total variance in work-related risk-taking behavior
