When employees have positive moods and feelings (called positive affect) in the workplace, they tend to be better at helping others, solving-problems, and taking risks. When a group of employees has positive group affect, they tend to have more cooperation, less conflict, less absenteeism, and higher individual well-being than groups with low positive affect. Today’s best managers know that group positive affect can be contagious. Group members share their positive emotions and that leads other employees to feel more positive in return. Unfortunately, the positive mood can get much higher than it should, and that can hurt performance, so today’s best managers help employees keep a healthy level of positive affect.
