Abstract: Many field office leaders contend that authoritarian leadership improves the performance of humanitarian operations. The common narrative is that authoritarian leadership helps aid workers more quickly adapt to changes and thus deliver better job performance (e.g., by improving operations in their field office). However, given that field reports often highlight extant leadership as the source of serious operational failures, could leaders with an authoritarian style be part of the problem? We draw on psychological theorizing on the nature of human motivation to address this question. Specifically, we note that many aid workers primarily join humanitarian operations with the prosocial motive to help beneficiaries. While proactive adaptability is inherent to prosocial motivation, we hypothesize that authoritarian leadership may curtail the relationship by impeding aid workers’ autonomy. We find support for our theorizing in a sample of 299 humanitarian aid workers from the field. Additionally, we conducted 31 expert interviews to contextualize and validate our empirical findings. The paper concludes by discussing the findings’ theoretical and managerial implications for humanitarian operations.

Abstract: Conducting organizational research via online surveys and experiments offers a host of advantages over traditional forms of data collection when it comes to sampling for more advanced study designs, while also ensuring data quality. To draw attention to these advantages and encourage researchers to fully leverage them, the present paper is structured into two parts. First, along a structure of commonly used research designs, we showcase select organizational psychology (OP) and organizational behavior (OB) research and explain how the Internet makes it feasible to conduct research not only with larger and more representative samples, but also with more complex research designs than circumstances usually allow in offline settings. Subsequently, because online data collections often also come with some data quality concerns, in the second section, we synthesize the methodological literature to outline three improvement areas and several accompanying strategies for bolstering data quality. Plain Language Summary: These days, many theories from the fields of organizational psychology and organizational behavior are tested online simply because it is easier. The point of this paper is to illustrate the unique advantages of the Internet beyond mere convenience—specifically, how the related technologies offer more than simply the ability to mirror offline studies. Accordingly, our paper first guides readers through examples of more ambitious online survey and experimental research designs within the organizational domain. Second, we address the potential data quality drawbacks of these approaches by outlining three concrete areas of improvement. Each comes with specific recommendations that can ensure higher data quality when conducting organizational survey or experimental research online.

Abstract: 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.

Abstract: 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.

Abstract: Practitioners repeatedly note that the everyday behavior of asking followers open questions and attentively listening to their responses is a powerful leadership technique. Yet, despite such popularity, these practices are currently under-theorized. Addressing this gap, we formally define the behavioral configuration of asking open questions combined with attentive listening as “Respectful Inquiry”, and then draw on Self-Determination Theory to provide a motivational account of its antecedents, consequences, and moderators within a leader-follower relationship. Specifically, we argue that Respectful Inquiry principally satisfies followers' basic psychological needs for competence, relatedness, and autonomy. Against this background, we highlight ironic contexts where Respectful Inquiry is likely to be especially rare, but would also be especially valuable. These ironic contexts include situations where interpersonal power difference, time pressure, physical distance, cognitive load, follower dissatisfaction, or organizational control focus are high. We additionally outline how the effect of Respectful Inquiry behaviors critically hinges upon the interaction history a follower has with a leader. More generally, we make the suggestion that the leadership field would benefit from complementing its traditional focus on “gestalt” leadership styles with research on concrete and narrow communicative behaviors, such as Respectful Inquiry.
