Leaders’ response to employee overqualification: An explanation of the curvilinear moderated relationship

Abstract

This research aimed to advance overqualification literature by examining how leaders’ perceived employee overqualification (LPEO) influences their empowering behaviour and employee work behaviours. Drawing upon the individualized leadership theory, we proposed that LPEO has an inverted U‐shape relationship with their empowering behaviour such that leaders are more motivated to empower employees from low to moderate levels of overqualification, but this tendency decreases after a certain inflection point. We also predicted that the inflection point occurs at a lower level of employee overqualification when leaders perceive higher (vs. lower) status threats. Leader empowering behaviour was hypothesized to positively predict employees’ voice and negatively predict their withdrawal behaviour. Two multi‐source and time‐lagged studies were conducted to examine this moderated mediation curvilinear model. In Study 1, survey data from 372 leader–employee dyads supported the inverted U‐shape mediation model from leaders’ perceived overqualification to empowering behaviour, then to employee outcomes (i.e., voice and withdrawal behaviour). In Study 2, we collected data from a sample of 73 team leaders and 286 employees, and the results supported the full model. Taken together, these findings offer a perspective to enrich the understanding of employee overqualification and have important practical implications. Practitioner points When leaders regard employees as overqualified, they can assist them via the means of appropriate empowerment to best utilize their skills to benefit the company. Leader empowerment can inspire employees’ voice behaviour but reduce their withdrawal behaviours. To minimize potentially negative aspects from highly overqualified employees, organizations should reduce leaders’ concern about the status threat, and encourage leaders’ proactive responses to these employees so as to achieve positive returns from overqualified employees.

“…It is usually assumed in the victimization literature that supervisors are of higher status than the victimized subordinate (Aquino & Thau, 2009; Tepper, 2000). Yet other literatures relax this assumption and allow for employees to be considered as higher status relative to their supervisor (e.g., Jiang et al, 2022; Triana et al, 2017; Yu et al, 2018). The theoretical arguments advanced in these articles seem to support the theory we develop—that higher status buffers employees from the deleterious acts of their supervisor.…”

The Curvilinear Effects of Leader Public Service Motivation on Person–Supervisor Fit and Subordinate Emotional Exhaustion: Evidence From Field and Experimental Studies

“…The indirect curvilinear effect was tested using Hayes and Preacher’s (2010) MEDCURVE Macro in Mplus Version 8.2 (Muthén & Muthén, 1998/2018). To test the curvilinear moderated mediation effects (i.e., the instantaneous indirect effects of leader PSM on employee emotional exhaustion via PS fit at low and high levels of employee PSM), this study followed the combined statistical procedures of Hayes and Preacher’s (2010) MEDCURVE and Edwards and Lambert’s (2007) bootstrapping-based approach with 10,000 samples (see also Jiang et al., 2022 for a detailed procedure).…”

“…To test our theoretical model, we adopted an ESM design to collect data. We recruited participants through an online platform, which was widely adopted by researchers (e.g., Jiang et al, 2022; Mihalache & Mihalache, 2022; Molina et al, 2022). Full‐time employees were eligible to participate in our surveys.…”
