"The Power of a Firm's Benevolent Act": The Influence of Work Overload on Turnover Intention, the Mediating Role of Meaningfulness of Work and the Moderating Effect of CSR Activities.

Although previous works have examined how work overload affects the perceptions, attitudes, and behaviors of members in an organization, those studies have paid insufficient attention to the mediating and contingent factors in the work overload-turnover intention link from the perspective of positive psychology. Considering the theoretical and practical value and importance of positive psychology, studies that use it to investigate underlying processes are needed. Also, existing studies on work overload have focused on the moderating role of individual-level variables to reduce the negative effects of work overload, mostly ignoring the importance of organizational-level moderators. To resolve those issues, we hypothesize that the meaningfulness of an employee's work mediates the relationship between work overload and turnover intention. Corporate social responsibility (CSR) practices could moderate the association between work overload and the meaningfulness of work. Using a three-wave data set gathered from 356 currently working employees in South Korea, we reveal not only that the meaningfulness of work mediates the work overload-turnover intention link, but also that CSR activities play a buffering role in the work overload-meaningfulness of work link. Our findings suggest that, from the perspective of positive psychology, the degree of meaningfulness of work (as a mediator) and CSR activities (as a moderator) function as intermediating mechanisms in the work overload-turnover intention link.
