The project manager should aim to resolve conflicts in a way that promotes understanding and cooperation among all team members. This involves understanding the emotions and perspectives of all parties involved, and finding ways to reduce tension and increase cooperation. Simply issuing warnings or sending individuals to training may not address the root cause of the conflict. Similarly, establishing special rules or treatment for certain individuals may not be fair or effective in the long term. The project manager should strive to create an environment where all team members feel heard, understood, and valued.
