Emotion in an organization is much more than a phenomenon experienced solely by its members - it is a deeply embedded component of the organizational fabric. Consistent with this idea, chapters in this volume deal with emotion at all levels of organizing: at the individual level, expressed in interpersonal exchanges and in groups, and across the organization as a whole. They represent a selection of papers from the Eighth International Conference on Emotion in Organizations, held in July 2012 in Helsinki, Finland; plus a selection of invited chapters. Chapters thus represent cutting-edge articles by leading and emerging scholars of emotion in organizations from around the world. Specific topics include creation of positively deviant business-to-business services, leader effectiveness and emotions in crisis situations, gender and role conflict among managers, developing shared well-being in communal settings, the nature of emotional labor across levels, managing workplace aggression, building customer passion, developing mindfulness, emergence of expectations, emotionalizing institutional theory, bullying as a form of institutional control, and how employees project competence.
