The need for ethical leadership in navigating today’s complex, global and competitive organisations has been established. While research has confirmed the importance of ethical leaders in promoting positive organisational and employee outcomes, scant research has examined the antecedents of ethical leadership. Furthermore, there has been a call for further examination of leadership models, particularly indigenous leadership models. Responding to these issues, this study suggests Māori leaders’ values add insights into enhancing ethical leadership. Three studies confirm the role of Māori values (...) and ethical leadership. Study one, based on kaupapa Māori research methods, is an exploratory 22-interview study of Māori leaders and identifies five values, as common to successful indigenous leaders. In study two, 249 employees rate their leaders on these five dimensions in relation to their ethical leadership and exchange relationships. Structural equation modelling shows strong support for the distinct nature of the five values and their positive influence on ethical leadership perceptions and quality exchange relationships. Study three, on 122 employees, reinforces the findings of study two—and demonstrates that LMX predicts job outcomes both indirectly and directly, with humility and collectivism also directly predicting outcomes. Our findings suggest that indigenous leaders’ values enhance perceptions and outcomes of ethical leadership for employees. (shrink)

In the present article, we argue that the constant pressure that leaders face may limit the willpower required to behave according to ethical norms and standards and may therefore lead to unethical behavior. Drawing upon the ego depletion and moral self-regulation literatures, we examined whether self-regulatory depletion that is contingent upon the moral identity of leaders may promote unethical leadership behavior. A laboratory experiment and a multisource field study revealed that regulatory resource depletion promotes unethical leader behaviors among leaders who (...) are low in moral identity. No such effect was found among leaders with a high moral identity. This study extends our knowledge on why organizational leaders do not always conform to organizational goals. Specifically, we argue that the hectic and fragmented workdays of leaders may increase the likelihood that they violate ethical norms. This highlights the necessity to carefully schedule tasks that may have ethical implications. Similarly, organizations should be aware that overloading their managers with work may increase the likelihood of their leaders transgressing ethical norms. (shrink)

Time pressure has been shown to have a negative impact on ethical decision-making. This paper uses an experimental approach to examine the impact of an antecedent of time pressure, whether it is anticipated or not, on participants’ perceptions of unethical behaviour. Utilising 60 business school students at an Australian university, we examine the differential impact of anticipated and unanticipated time deadline pressure on participants’ perceptions of the likelihood of unethical behaviour occurring. We find the perception of the likelihood of unethical (...) behaviour occurring to be significantly reduced when time pressure is anticipated rather than unanticipated. The implications of this finding for both professional service organisations and tertiary institutions are considered. (shrink)

While the link between servant leadership and organizational citizenship behavior has been established, the individual-level mechanisms underlying this relationship and its boundary conditions remain poorly understood. In this study, we investigate the salience of the mediating mechanisms of leader–member exchange and psychological empowerment in explaining the process by which servant leaders elicit discretionary OCB among followers. We also examine the role of followers’ proactive personality in moderating the indirect effects of servant leadership on OCB through LMX and psychological empowerment. Analysis (...) of survey data collected from 446 supervisor–subordinate dyads in a large Chinese state-owned enterprise suggests that while servant leadership is positively related to subordinate OCB through LMX, psychological empowerment does not explain any additional variance in OCB above that accounted for by LMX. Moderated mediation tests confirm the moderating effect of proactive personality through LMX. By providing a nuanced understanding of how and when servant leadership leads followers to go above and beyond their job role, our study assists organizations in deciding how to develop and utilize servant leaders in their organizations.

Most research on ethical leadership to date investigates the consequences of ethical leadership rather than its antecedents. Here, we aim to contribute to this field by studying leader personality as a potential antecedent of ethical leader behavior. In two multisource studies, we investigated the relationships between personality traits and ethical leader behavior. Leader personality was measured through self-ratings using the five-factor personality framework. Two subordinates rated their leaders' ethical behavior. Study 1 used a unidimensional Ethical Leadership Scale (ELS). In study (...) 2 we used this scale as well as an instrument distinguishing three different ethical leader behaviors, namely, fairness, role clarification, and power sharing. Further, in study 2 we controlled for the influence of the relationship between leader and followers (LMX). As expected, conscientiousness and agreeableness were most consistently related to ethical leadership. In study 1, after controlling for the other personality traits, conscientiousness related positively with ethical leadership. In study 2, after controlling for other traits and LMX, conscientiousness related positively with ethical leadership and the behavior role clarification, and agreeableness with power sharing and fairness. Also, emotional stability related positively with ethical leadership and role clarification after controlling for LMX. As expected, openness to experience and extraversion were unrelated to ethical leader behaviors. (shrink)

In this study, we examine the nature of the relationship between ethical leadership and unethical pro-organizational behavior (UPB), defined as unethical behavior conducted by employees with the aim of benefiting their organization, and whether the strength of the relationship differs between subordinates experiencing high and low identification with supervisor. Based on three-wave survey data obtained from 239 public sector employees in China, we find that ethical leadership has an inverted u-shaped (curvilinear) relationship with UPB. As the level of ethical leadership (...) increases from low to moderate, UPB increases; as the level of ethical leadership increases from moderate to high, UPB decreases. Further, we find that the strength of this inverted u-curve relationship differs between subordinates with high and low identification with supervisor. That is to say, the inverted u-shaped relationship between ethical leadership and UPB was stronger when subordinates experienced high levels of identification with supervisor. The theoretical and managerial implications of our findings for understanding how to manage UPB in an organizational context are discussed. (shrink)

In this study, we propose and test a model of the effects of organizational ethical culture and organizational architecture on the perceived unethical behavior of employees towards customers. This study also examines the relationship between organizational ethical culture and moral acceptability judgment, hypothesizing that moral acceptability judgment is an important stage in the ethical decision-making process. Based on a field study in one of the largest financial institutions in Europe, we found that organizational ethical culture was significantly related to the (...) perceived frequency of unethical behavior towards customers and to the moral acceptability judgment of this type of unethical behavior. No support was found for the claim that features of organizational architecture are associated with the perceived frequency of unethical behavior towards customers. This is the first study to document the differential effects of organizational architecture and organizational ethical culture on perceived unethical behavior of employees towards customers, in wholesale banking. Implications for managers and future research are discussed. (shrink)
