A team member has experienced personal conflicts on past projects, making them nervous about working on the current project. The project manager knows this team member could add value to the project.

Simply advising against sharing personal information doesn't address the team member's nervousness or help them move past their past experiences to contribute value.

Consulting the project sponsor about sharing personal information is inappropriate and unnecessary, as the focus should be on helping the team member perform, not on their past personal issues.

The project manager's role is to motivate and guide team members; encouraging the team member to focus on the present and reframe past conflicts as learning opportunities helps them overcome anxiety, build confidence, and contribute effectively to the current project.

Consulting HR is an escalation that implies a disciplinary or formal issue, which is not the case here; the project manager should first attempt to resolve such issues through direct coaching and support.
