Employees Empowered to Report

MPC views its people as its greatest assets. It's why our company empowers employees by fostering a "speak-up culture" in which employees feel heard, validated and safe when reporting business ethics and compliance issues.

Employees are empowered to report suspected wrongdoing and are protected from retaliation for good faith reporting under Policy #2007 - Anti-Retaliation for Reporting Illegal or Unethical Conduct. In the event retaliation is verified, appropriate corrective actions will be taken, up to and including termination.

Watch the Employees Empowered to Report video for more information on reporting and be sure to keep the Code of Business Conduct and our commitement to integrity top of mind as you make decisions on behalf of the company and yourself.
