In recent years, scholarly interest in the role of emotions in the workplace has been rapidly increasing. Whereas early research focused on individuals’ emotions as outcomes of workplace events, more recent studies have demonstrated that the emotions expressed by organizational members can also impact the perceptions, attitudes, and behaviors of others. However, the literature on the interpersonal effects of emotions is still in its infancy; we lack a precise understanding of when and how such interpersonal influence occurs. Drawing upon multiple theoretical perspectives and methodologies, this symposium brings together leading experts to provide new insights that can contribute to a richer and more precise understanding of the interpersonal effects of emotions in the workplace. Specifically, the presentations in this symposium (a) examine individual and personality differences (e.g., implicit theories of personality, cultural background) that influence how an observer responds to another person’s emotions, (b) identify important emotion characteristics (e.g., intensity, target, complexity) that moderate the effects of emotions on employees’ attitudes and behaviors, (c) highlight cognitive and affective mechanisms (e.g., inferences, attitude formation) linking antecedents to outcomes, and (d) identify a range of organizationally-relevant outcomes of expressing and observing emotions in the workplace (e.g., cooperation, relationship satisfaction, leadership effectiveness). In addition, the symposium will include an interactive discussion and question period aimed at shedding further light on these issues and identifying future research avenues.
