The direct and indirect effects of work characteristics on self-reported safe working were investigated in a longitudinal study of frontline manufacturing employees (N = 161). The work characteristics included job autonomy, role overload, role conflict, supportive supervision, training adequacy, job security, and communication quality. Job autonomy and communication quality were positively associated with safe working after prior levels of these variables were controlled for, and supportive supervision had a lagged positive effect on safe working 18 months later. Additional analyses showed that organizational commitment fully mediated the effect of job autonomy on safe working and partially mediated the effect of communication quality on safe working. The study suggests that work characteristics are important antecedents of safe working.
