Description:
<jats:p>The construct of heavy-work investment (HWI) is bi-dimensional, revolving around the investment of both time and effort at work. The current paper expands the research thinking and joins the pioneering studies that explore HWI as a relatively new concept in the work-related literature (since 2012). The prime aim of this conceptual paper is to develop a model regarding the intricate relationships between the dimensions of HWI and their work outcomes (with emphasis on possible conditional factors). In particular: (1) we refine the definition of HWI by accounting for the different levels of time and effort investment and (2) we outline multiplex propositions with regard to possible (positive and negative) outcomes of HWI, considering different moderators that can potentially impact these associations. Finally, we offer practical implications for human resource management.</jats:p>
