Christian Tröster is a tenured Full Professor of Leadership and Organizational Behavior. He trained first as a sociologist at the University of Groningen and then earned his PhD in management at the Rotterdam School of Management, Erasmus University, with an early academic position in Singapore and research stays in the United States, Canada, and New Zealand.
His research examines how people respond to those who lead them, and how diversity, social comparison, and emotion shape those responses. A recurring theme is that leadership's effects are often counterintuitive: his work on abusive supervision, for instance, finds that mistreated employees can respond not with retaliation but with guilt, and even with help directed back at the supervisor who mistreats them. Related work spans status and social comparison, identity and diversity in teams, and the effects of hybrid work on workplace relationships — often less than the rush back to the office assumes. His current work turns to AI, asking how employees respond when they treat it as a social presence rather than a tool, and what that means for leadership.
His work, which favors multi-method designs that test theory against how people actually behave at work, appears in the field's leading journals, including the Academy of Management Journal, the Journal of Applied Psychology, the Journal of Personality and Social Psychology, the Journal of Management, the Journal of Management Studies, the Journal of International Business Studies, and Organizational Behavior and Human Decision Processes.
He served as an Associate Editor of the Academy of Management Journal (2022–2025) and now sits on its Editorial Board. Prof. Tröster teaches leadership, cross-cultural management, and research design at every level, from bachelor's students to executives and across three continents, aiming to develop evidence-based managers — work recognized with an Exceptional Teacher Award in 2025. He also helps building the research skills of academics around the world, writing on research methods, running paper-development workshops, and developing tools that help researchers turn ideas into publishable work.

Selected Publications
A consensus in the literature has converged on the idea that one's perceptions of being treated better by a leader (compared with one's coworkers' treatment by the same leader) motivate prosocial behaviour. Drawing on current theory of hubristic pride and its evolutionary role in status maintenance, we challenge this consensus by proposing that favourable, downward social comparisons of leader-member exchange (i.e., leader-member exchange social comparisons; LMXSC) can also lead to social undermining. Specifically, we argue that, in individuals with high trait dominance, LMXSC triggers hubristic pride, which, in turn, motivates social undermining. Results from two experiments and a longitudinal field study support this idea. In sum, our work shifts the consensus in LMXSC theory by showing when and why high LMXSC can motivate negative coworker-directed behaviour, and it also offers practical help to organizational leaders dealing with the ethical decision of if, and when, to preferentially treat individual team members.
We investigated the turnover intentions of employees who perceive that they are being treated with more or less abusive supervision than their coworkers. We call this incongruent abusive supervision. Our findings support our theory that employees associate incongruent abusive supervision with anticipation of social exclusion from their coworkers. Furthermore, this appraisal of social exclusion threat is associated with feelings of shame, which, in turn, increase turnover intentions. Two experimental vignettes provide support for our theoretical model. These findings highlight coworkers’ abusive supervision as an important context for the experience of one’s own abusive supervision and introduce shame as an emotional mechanism important for understanding employee responses to incongruent abusive supervision.
Studies on abusive supervision typically posit that targets of abuse will either directly blame the perpetrating supervisor or indirectly blame the organization for allowing the abuse, and as a result reduce their cooperativeness at work. We pivot from this predominant logic and argue that, under certain circumstances, targets of abusive supervision may blame themselves, feel guilty, and then try to make it up to their abusive supervisors by helping them more. Drawing on the emotional process theory of abusive supervision and the more general socio-functional perspective of emotions, we specify that such a dynamic is more likely to ensue when subordinates otherwise experience the relationship with their supervisors as good (high LMX). Two studies—an experiment and a two-weeks bi-daily experience sampling study—provide support for our reasoning. As such, our study extends theorizing on the consequences of abusive supervision, which has typically found that it reduces cooperative behaviors. Moreover, it contributes to previous speculations that leaders may engage in abusive supervision because it has beneficial consequences for them.
Research has shown that employees who occupy more central positions in their organization's network have lower turnover. As a result, scholars commonly interpret turnover as the consequence of social networks. Based on Conservation of Resources theory, we propose an alternative coevolution perspective that recognizes the influence of changes in individuals' social network position on their thoughts of quitting (the consideration of turnover), but also posits that thoughts of quitting shape individuals' agency in maintaining and changing their social network. Extending previous research, we predict that creation (dissolution) of both friendship ties and advice ties are negatively (positively) related to subsequent thoughts of quitting. We then develop and test the novel hypotheses that for friendship ties, thoughts of quitting are positively related to tie retention and negatively related to tie creation (leading to network stasis), whereas for advice ties thoughts of quitting are negatively related to tie retention and positively related to tie creation (leading to network churn). In a longitudinal network analysis that assessed 121 employees across three time points, we find support for our hypotheses that thoughts of quitting affect network changes, but do not find that network changes affect thoughts of quitting.
The extant social undermining literature suggests that employees envy and, consequently, undermine coworkers when they feel that these coworkers are better off and thus pose a threat to their own current status. With the present research, we draw on the sociofunctional approach to emotions to propose that an anticipated future status threat can similarly incline employees to feel envy toward, and subsequently undermine, their coworkers. We argue that employees pay special attention to coworkers' past development in relation to their own, because faster-rising coworkers may pose a future status threat even if they are still performing worse in absolute terms in the present. With a set of two behavioral experiments (N = 90 and N = 168), we establish that participants react to faster-rising coworkers with social undermining behavior when the climate is competitive (vs. less competitive). We extended these results with a scenario experiment (N = 376) showing that, in these situations, participants extrapolate lower future status than said coworker and thus respond with envy and undermining behavior. A two-wave field study (N = 252) replicated the complete moderated serial mediation model. Our findings help to explain why employees sometimes undermine others who present no immediate threat to their status. As such, we extend theorizing on social undermining and social comparison.
