Background:
This study investigates the determinants of long working hours from the perspectives of the demand-control model [Karasek, 1979] and social exchange theory [Blau, 1964; Goulder, 1960].
Objective:
These two theoretical perspectives are tested to understand why individuals work longer (or shorter) hours.
Methods:
The hypotheses are tested with a representative sample of 1,604 employed Canadians.
Results:
In line with Karasek's model, the results support that high job demands are positively associated with longer work hours. The social exchange perspective would predict a positive association between skill discretion and work hours. This hypothesis was supported for individuals with a higher education degree. Finally, the results support a positive association between active jobs and longer work hours.
Conclusions:
Our research suggests that job demands and social exchange dynamics need to be considered together in the explanation of longer (or shorter) work hours.
