Purpose -Job engagement has attracted much attention recently. However, very little research distinguishes between how the context may affect different engagement dimensions differently. Based on a theory of resource exhaustion, the purpose of this paper is to focus on a cognitively demanding work context in order to explore variations in effect of different engagement dimension and different expatriate work outcomes. Design/methodology/approach -The authors use survey results from 102 expatriate academics in Singapore to study the relations between job engagement and expatriate work outcomes. Contrary to most studies, the authors examine physical, emotional, and cognitive engagement separately. Findings -The authors found that for expatriate academics, the different dimensions of job engagement have different relationships with work outcomes such that physical engagement and emotional engagement are positively associated with various work outcomes while cognitive engagement is negatively related or not associated at all with the same work outcomes. The authors explain the variation in results by drawing on recent developments in social cognitive neuroscience. Originality/value -This is one of the first empirical studies to examine job engagement in an international setting and the application of a social cognitive neuroscience provides a novel perspective. An engagement theory of resource exhaustion could enhance theory building as well as facilitate the understanding of the association between job engagement and work outcomes in varying contexts.
