The Influence of Leadership on Employees' Work-nonwork Interface and Wellbeing: A Scoping Review.

Many current working conditions are characterized by increasing blurred boundaries between work and nonwork with spillover that impact employees' and recovery processes and wellbeing. Research, although emerging, considers these processes in the leadership-wellbeing relationship insufficiently. The main aim of this study, therefore, was to enhance our understanding of the role of leadership on employee's work-nonwork interface and wellbeing. To address these processes adequately, longitudinal research is most appropriate. To our best knowledge, no review exists that could inform longitudinal studies on the leadership-employee wellbeing relationship with a focus on spillover and recovery processes. Following the PRISMA Extension for Scoping Reviews, we apply a narrative synthesis of 21 identified studies to organize the research landscape. We make three main contributions: First, we adopt an integrated resource-demands based process perspective and expand the leadership-employee wellbeing relationship by including spillover and recovery. Second, we map the used theoretical approaches and analyzed research gaps. Third, we offer a list of the issues and potential remedies of applied methodologies to orient further research. Results show, that while work-nonwork research is predominantly approached from a negative conflict-based view, research focused more on positive than on negative leadership. We identify two broad categories of investigated mechanisms, namely bolstering/hampering mechanisms, and buffering/strengthening mechanisms. Findings also highlight the importance of personal energy resources and therefore call for more attention to affect-driven theories. The identified predominance of the IT and healthcare sectors and of working parents warrants more representative research. We offer recommendations to advance future research both theoretically and methodologically.
