We propose that an employee's bottom-line mentality may have an important effect on social undermining behavior in organizations. Bottom-line mentality is defined as 1-dimensional thinking that revolves around securing bottom-line outcomes to the neglect of competing priorities. Across a series of studies, we establish an initial nomological network for bottom-line mentality. We also develop and evaluate a 4-item measure of bottom-line mentality. In terms of our theoretical model, we draw on social-cognitive theory (Bandura, 1977, 1986) to propose that supervisor bottom-line mentality is positively related to employee bottom-line mentality (Hypothesis 1). On the basis of conceptual arguments pertaining to bottom-line mentality (Callahan, 2004; Wolfe, 1988), we hypothesize that employee bottom-line mentality is positively related to social undermining (Hypothesis 2). We further predict a moderated-mediation model whereby the indirect effect of supervisor bottom-line mentality on social undermining, through employee bottom-line mentality, is moderated by employee core self-evaluations and conscientiousness (Hypothesis 3). We collected multisource field data to test our theoretical model (i.e., focal-supervisor-coworker triads; N = 113). Results from moderated-mediation analyses provide general support for our hypotheses. Theoretical and practical implications of bottom-line mentality and social undermining are discussed, and areas for future research are identified.

Summary The current research explores supervisor‐level antecedents of abusive supervision in the workplace. Specifically, this study introduces affective events theory to the abusive supervision literature to suggest that supervisor role overload, a work‐related event, leads to supervisor frustration. As an intense negative emotional reaction, frustration, in turn, triggers supervisors to exhibit abusive behaviors in the workplace. Supervisor personality traits—namely, neuroticism, conscientiousness, and agreeableness—are also posited to moderate these hypothesized relationships. Specifically, neuroticism is expected to moderate the relationship between role overload and frustration while conscientiousness and agreeableness are expected to moderate the relationship between frustration and abusive supervision. Ultimately, we propose and examine a moderated‐mediation model. Multisource field data demonstrate general support for the hypothesized relationships. We conclude with theoretical and practical implications as well as future research avenues. Copyright © 2016 John Wiley & Sons, Ltd.

Based on earlier taxonomies of group composition models, aggregating data from individuallevel responses to operationalize group-level constructs is a common aspect of management research. The present study contributes to the literature on group composition models by quantitatively integrating the climate literature via meta-analysis to determine which of the two most common methods of aggregation, direct consensus and referent-shift consensus, is the stronger predictor of group-level outcomes. We found that referent-shift consensus was a stronger predictor of job performance and customer service performance than direct consensus. However, we found that direct consensus was a stronger predictor of job attitudes than referent-shift consensus. We also found that climate-performance relationships were moderated by aggregation method of the performance criterion. The implications of these findings for advancing multilevel theory and research are discussed.

This study seeks to advance the bottom‐line mentality literature by exploring an antecedent and outcome of employee bottom‐line mentality. We build and test a moderated‐mediation model by arguing that the personality trait of Machiavellianism promotes an employee's adoption of a bottom‐line mentality. Moreover, drawing on trait activation theory, we argue that this relationship is fully activated when the employee perceives that the organisation endorses a bottom‐line mentality. To expand our theoretical model, we also suggest that employee bottom‐line mentality inhibits organisational citizenship behaviour directed towards co‐workers. Lastly, we investigate whether an employee's perception of an organisation's bottom‐line mentality conditionally moderates the indirect effect of Machiavellianism on organisational citizenship behaviour directed towards co‐workers through the mediated mechanism of employee bottom‐line mentality. Our theoretical model is tested across two distinct studies. Study 1, a field study conducted within a variety of organisations, provides evidence for our initial predictions (Hypotheses 1 and 2). Study 2, a multisource field study conducted in multiple industries, replicates and extends the findings from Study 1 by providing evidence for the entire moderated‐mediation model. We find support for our hypothesised model across both studies. Implications for theory and practice are discussed, and suggestions for future research are identified.
