In this study, we examined the relationships among personal resources (i.e., psychological capital, perceived employability, and career resources), constraints, and work volition of university students. Two undergraduate samples from the United States and Hong Kong were collected. In both samples, results showed that personal resources were positively associated with work volition, whereas constraints were negatively related to it. However, moderated regression analysis with the two samples exerted only limited support on the moderating effect of personal resources in mitigating the effect of constraints on work volition. Limitations and implications were also discussed.
