title: The moderating effect of control over work scheduling and overtime on the relationship between workload demands and perceived job risk.
abstract: BACKGROUND
  This study investigated the impact of workload demands on perceived job risk using the Job Demand-Control model as a research framework.
  
  
  OBJECTIVE
  The primary objective was to test the hypothesis that employee control over work scheduling and overtime would moderate the relationship between workload demands and perceived job risk.
  
  
  METHODS
  Ninety-six participants working in a variety of industries completed measures of workload demands, and of control over work scheduling and overtime, and a measure of perceived job risk.
  
  
  RESULTS
  Workload demands predicted higher perceptions of job risk. However, the results also suggest that control over overtime moderated this relationship, where those with the combination of high workload demands and low control over overtime reported higher levels of perceived risk. The results indicate that the JDC model is applicable to safety research.
  
  
  CONCLUSIONS
  The results suggest that employee control over workload demands is an important variable to consider in terms of managing workplace safety. The present study also points to important areas for future research to explore in order to further understand the connection between demands and safety.
