Abstract: Over the last decade until recent years, work engagement has captured a lot of interest among many; academician, industry, consultancy and the like for its positive impact towards work attitudes. To add compendium knowledge on the area, a lot of previous studies have made attempt to conduct work engagement studies on numerous work variables and also in different settings. Despite numerous studies, only few studies have made attempt to posit work engagement as a mediator role. Moreover, with the growing concern on the increasingly crucial aspects of work variables; career growth and organizational citizenship behavior, little is known on how work engagement can propose linkage between the two. In this article, I review sets of literature to propose possible linkage on such relationship. To offer explanatory device, I review and discuss related theories and concepts to provide direction and sense of the possible linkage.
