Based on the grounds of the Theory of Woking Psychology, this study examined the effect of economic constraints on decent work perception among undergraduates in Vietnam. The data was collected from 300 students coming from two of the biggest universities in Vietnam, mostly majoring in economics or engineering. Utilizing SEM methodology, this study discovered that economic constraints have a positive relation to decent work. The result also demonstrated the important role of proactive personality in moderating this relationship. The findings differ from previous studies, which showed a negative relationship between economic constraints and decent work. Nevertheless, this study offers reasonable explanations so that the results are acceptable in the context of Vietnam. Based on the primary findings, some recommendations are given in order to help college students increase their prospects of obtaining decent work.
