To ensure that team members do not engage in self-serving behavior, the following measures can be taken: 1. **Establish clear values and culture**: Promote the values of collaboration and solidarity, encourage team members to support each other, and emphasize that the core of team success is collective effort rather than individual achievement. 2. **Set clear goals and reward mechanisms**: Define clear team goals and link reward mechanisms to team performance. In this way, team members will work hard for the common good. 3. **Strengthen communication**: Hold regular communication meetings to ensure that team members can express their opinions, share ideas and feedback, and reduce the chances of misunderstanding and dissatisfaction. 4. **Encourage openness and transparency**: Create an open and transparent environment where everyone has the opportunity to participate in the decision-making process and understand the operation of the team. 5. **Provide training and development opportunities**: Help team members improve their emotional intelligence and cooperation skills through training, and ensure that they understand the importance of teamwork. 6. **Build trust and responsibility**: Cultivate trust and commitment among team members, and emphasize the impact of individual behavior on the team as a whole. 7. **Leadership example**: Managers and leaders should set an example of cooperation and selflessness, and demonstrate the expected behaviors and attitudes by example. 8. **Timely feedback and correction**: Provide timely feedback and handling of inappropriate behavior to ensure that all team members understand what behavior is unacceptable. Through these measures, the spirit of cooperation among team members can be promoted and the occurrence of selfish behavior can be reduced.
