His work on workaholism and the overwork culture/climate of workplaces has earned recognition from the Association of Korean Management Scholars at the Academy of Management, receiving the Samsung Economic Research Institute (SERI) Best Paper Award, and has been supported by various research grants, including the Arnold O. Beckman Research Award funded by the University of Illinois Urbana-Champaign.

Now always helpful: Linking intrateam helping types to team effectiveness from a role theory perspective

Journal of Management

Lee, SH., Liu, Y., Koopmann, J., Seo, J. Y., Zhou, L., & Yu, Y.


Existing research on intrateam helping has predominantly taken a positive view on its impact on teams, overlooking the potential negative consequences that helping may elicit. To account for divergent implications of intrateam helping, we differentiate two types of helping that can manifest during teamwork: team autonomous helping and team dependent helping. Integrating this dual-type view of helping with a role theory perspective on teamwork, we propose a theoretical model that delineates the relationships among team goal orientations, two types of intrateam helping, team role-based functions (i.e., team role overload, team role coordination, and team role breadth self-efficacy), and team effectiveness. To test our model, we conducted two multi-wave survey studies, including 110 student project teams (Study 1) and 80 manufacturing teams in a pharmaceutical company (Study 2). Overall, the results showed that team autonomous helping benefited team role-based functions and ultimately team effectiveness, whereas team dependent helping hindered them. We also found that team learning goal orientation drove the occurrence of team autonomous helping in both studies, while team performance goal orientation drove team dependent helping in Study 1. By distinguishing between autonomous and dependent types of intrateam helping, and examining their unique motivational roots and divergent implications for teams, this research advances the extant literature by providing a more balanced account of the nature of helping in teams.

Struggling to stay engaged during adversity: A daily investigation of frontline service employees’ job insecurity and the moderating role of ethical leader behavior

Journal of Business Ethics

Lee, SH., Hur, W., Shin, Y.


Drawing on conservation of resources theory, this study examined the moderating role of ethical leader behavior in the effects of daily perceived job insecurity on work outcomes the next day (i.e., work engagement and customer-directed helping) through occupational regret the next morning among frontline service employees working in adverse work situations (i.e., the coronavirus disease pandemic). Using experience sampling method, data were collected from 135 frontline service employees across five consecutive workdays. The results showed that daily perceived job insecurity had a negative indirect effect on work engagement and customer-directed helping the next day through (increased) occupational regret the next day in the morning. In addition, ethical leader behavior moderated the negative indirect effect of daily perceived job insecurity on next-day work engagement and customer-directed helping through next-morning occupational regret. Specifically, these negative effects were especially stronger among employees who had observed low levels of ethical leader behavior the previous day. The theoretical implications of the present findings for researchers and their practical implications for managers are discussed.
