In this article, we theoretically develop and test the temporal intricacies of job engagement. Drawing on the attention view of social cognition, we examine the interplay of employees’ temporally relevant perspectives of fit (i.e., retrospected, current, and anticipated) within their ongoing membership to the organization. Utilizing field data gathered from a large multinational company over multiple time periods, we found support for a conditional indirect effect model. Specifically, our findings showed that current needs-supply (NS) fit accounted for two of the previously investigated antecedents of job engagement (i.e., psychological meaningfulness and safety), especially when organizational identification was low. Moreover, anticipated perceptions of NS fit fully mediated the influences of psychological meaningfulness and availability on job engagement. The mediating effect relating to psychological availability was also especially pronounced when organizational identification was low. By shedding light on employees’ temporally constructed psychological experiences, our research suggests that job engagement is not only affected by employees’ contemporaneous understandings of their jobs but also influenced by their perceptions of anticipated opportunities.
