Abstract
The present research investigates the mediational mechanism of Heavy-Work Investment (HWI) between job engagement, managerial roles and work burnout. The paper proposes an expansion to the HWI model (as divided into two dimensions: the investment of time and efforts) by exploring the role of value congruence (between the employees and their workplaces) as a moderator, with a two-study cultural differences perspective. Data from 186 American employees (Study 1) and 221 Israeli employees (Study 2) were collected. Moderated-mediation analyses were employed using PROCESS macro for the SPSS. Among others, we found that job engagement positively associates with HWI, but negatively with burnout. Managerial position was not related to any of the variables in either sample. However, the two HWI dimensions display different relationships with burnout; while the investment of efforts at work shows negative links to burnout, the investment of time does not show any consistent correlations with it. Moreover, support for moderated-mediation model was only found in the Israeli sample.. Implications and future research suggestions are discussed.
