Use group dynamics
All employees should be recognized as an active part of the team. Regardless of performance or role, everyone should have a say. In every group, there are special roles, e.g., the “informal leader” to whom the team orients itself, or the “adversary” who criticizes particularly frequently. The former can be given special responsibility by the manager and built up as a right-hand man. The latter can be involved by the manager by showing him special appreciation. Recognizing and involving special roles instead of excluding them promotes satisfaction and performance in the group.
