Beyond workaholism: Towards a general model of heavy work investment☆

Although the term workaholism is widely used, little consensus exists about its meaning, and there is a great need for further theoretical and methodological advancement. We attempt to address this need by introducing the concept of Heavy Work Investment (HWI), and viewing workaholism as only one of its subtypes. Furthermore, we propose a model consisting of four main components: HWI, its possible predictors, its types, and its outcomes. In this model, using Weiner's (1985) attributional framework, we differentiate between situational and dispositional types of HWI, each with its own subtypes, as based on the predictors of such an investment. For example, financial-needs-based and employer-directed are situational subtypes, whereas workaholism and work-devotion are dispositional subtypes. Based on the proposed HWI model, we compare dispositional investors with situational investors. Finally, the measurement of HWI, as well as future research directions (study of situational investors, research across time and cultures, and exploration of inter-generational similarity/ difference) is also discussed. © 2011 Elsevier Inc.
