The project manager should try to resolve the conflict between the supervisor and the workers by communicating the company culture and values, and how they affect the project objectives and stakeholder satisfaction. The project manager should also seek to understand the supervisor's perspective and goals, and find a way to align them with the project team's needs and expectations. This approach is consistent with the PMBOK Guide's recommendations on managing stakeholder engagement, conflict management, and leadership skills12.
