Perceived supervisor support is widely studied in terms of its positive outcomes. This paper, in contrast, investigates employees’ unethical pro-supervisor behavior as a negative consequence of perceived supervisor support. Drawing upon the multifoci approach of social exchange theory and the reciprocity principle, we hypothesized that perceived supervisor support can engender unethical pro-supervisor behavior via employees’ feelings of reciprocity towards the supervisor. Building on the instrumental reasons that underlie social exchanges, we further hypothesized that this mediation relationship is stronger for employees (...) high in Machiavellianism. We collected data for three experimental studies from full-time MBA students of a European business school and from U.S. working professionals, and the results provided consistent support for our proposed model. Taken together, the current study highlights the “dark side” of perceived supervisor support, in that it can lead to unethical behavior and that this effect can be accentuated by employees’ Machiavellianism.

This study seeks effective ways for managing employees with a high Machiavellian personality in organizations by identifying how to enhance their pro-organizational attitudes and behaviors [organizational citizenship behavior ] through transformational leadership. Drawing upon the dual-focused model of TFL, we suggest that exerting TFL upon employees high in Machiavellianism involves ethical dilemmas in that individual-focused and group-focused TFL have contrasting effects on leading pro-organizational attitudes/behaviors among these pro-individual employees. Analysis of data from 184 employees working in South Korea shows that (...) Machiavellianism negatively relates to affective commitment, OCB toward the organization, and OCB toward individuals, but positively to continuance commitment. More importantly, the results reveal that group-focused TFL can effectively manage employees high in Machiavellianism by mitigating the negative relations between Machiavellianism and affective commitment and between Machiavellianism and OCB-O. However, individual-focused TFL strengthens these negative relations as well as the negative relation between Machiavellianism and OCB-I. This study thus shows that to lead employees high in Machiavellianism in a pro-organizational direction, group-focused TFL rather than individual-focused TFL needs to be employed. (shrink)

Individuals with high levels of narcissism often ascend to leadership positions. Whereas there is evidence that narcissism is linked to unethical behavior and negative social outcomes, the effects of leader narcissism on an organization’s most important resource—its employees—have not yet been studied thoroughly. Using theoretical assumptions of the Narcissistic Admiration and Rivalry Concept and social exchange theories, we examined how leaders’ narcissistic rivalry was related to follower outcomes in a sample of matched leaders and followers. Followers of leaders high in (...) narcissistic rivalry reported less perceived supervisor support, lower quality leader-member relationships, lower performance-based self-esteem, and lower job engagement. These effects were only found when follower-rated leaders’ narcissistic rivalry was used in the model but not when self-rated leaders’ narcissistic rivalry was used as a predictor. This implies that the negative effects of leaders’ narcissistic rivalry on followers are driven by the expression of narcissistic tendencies. Leader development should thus focus on changing destructive leader behavior. We propose that leaders high in narcissistic rivalry can be motivated to make such changes by showing them that by hurting their followers, they will eventually undermine their own reputation and status. Furthermore, selection and promotion practices should incorporate objective measures to weaken the effects of narcissists’ self-promotional tactics in these contexts and thus prevent people high in narcissistic rivalry from rising to leadership positions.
