In project management, it's important to maintain a flexible and collaborative approach. If a team member's personal commitments change, the project manager should reassess the team's hours collaboratively to ensure that the project is not impeded by the issue. This approach respects the individual's personal commitments while also ensuring that the project continues to progress effectively. It's about finding a balance that works for everyone.
