摘要:The purpose of this paper is to bring conceptual clarity to the heavy work investment (HWI) construct while building a model based on a review of extant empirical and theoretical research and to encourage further discussion and investigations regarding the nature of HWI, specifically its individual level antecedents, dimensions, and outcomes for both the employee and the organization. The proposed theoretical framework builds upon the Job Demands–Resources model and conceptualizes HWI on a continuum of workaholism and work engagement. Specific propositions for the antecedents and outcomes of the HWI continuum are developed. The paper ends with a discussion of future research directions.
