The purpose of the current study was to investigate the impact of job demands on health and work outcomes among Malaysian workers. We hypothesized that job demands (i.e., emotional demands and physical demands) would predict future work‐related burnout and work engagement, in turn affecting sleep problems and job performance (in‐role, extra‐role). A longitudinal two‐wave survey was conducted among Malaysian workers and valid data from 345 participants were analyzed using structural equation modeling. The results revealed that work‐related burnout predicts sleep problems while work engagement increased employees' job performance over time. Overall, the current study highlights the importance of specific job demands (i.e., emotional demands and physical demands) that specifically affect health‐related behavior and work‐related behavior among workers.
