Besides the material advantages that happy employees reap, they accrue additional benefits in the form of interpersonal rewards. For example, people who experience more positive emotions receive more social support from both colleagues and supervisors (Iverson et al., 1998). One explanation for this finding is that it is pleasant to help others who are generally positive and cheerful. Or coworkers may offer support because happy workers tend to be cooperative (Miles et al., 2002). For example, happy chief executives with managerial teams also high in positive affect experience relatively less conflict and more cooperation (Barsade, Ward, Turner, & Sonnenfeld, 2000)
