Document the unethical behavior in detail, but take no immediate action, waiting to see if the situation resolves itself over time to avoid confrontation.

Discuss the situation privately with the team member, explain the ethical concerns, and work together to find a resolution that aligns with the project's and organization's ethical standards.

Address the unethical behavior during a team meeting, using the situation as an example to reinforce the importance of ethical conduct in the project.

Report the team member's unethical behavior to senior management and let them handle the situation, focusing solely on delivering project results.
