Multivariate analyses confirmed that task demands of heavy labor were associated with workplace injury above baseline individual and job characteristics. Consistent with previous research, results indicated worker control was associated with increased health. Reliable co-workers were associated with less exhaustion, and working fast was associated with greater exhaustion. My results implied that …
