Explanation:

Uncooperative group members may not realize that they’re failing to fulfill role expectations. Vague job descriptions, inadequate onboarding and weak leadership contribute to role confusion. The annoying know-it-all who takes over the meeting may be trying too hard to fit in. The slacker may need positive reinforcement and encouragement.
Uncooperative and blatantly resistant group members slip into a pattern of bad behavior and get worse if not challenged. The best time to address uncooperative behavior is when it occurs, not days or weeks later after you’ve been fuming about it and grousing to others.
f patience, understanding and coaching fail to achieve the desired results, consider tough love. All group members should be held accountable for their actions and outcomes. Explain what needs to change, identify a timeline for making changes and identify possible consequences if nothing changes.
