IX. Questions; Reporting Violations
Employees should speak with anyone in their management chain or the Legal Department when they have a question about the application of the Code of Conduct or when in doubt about how to properly act in a particular situation.
The Amazon.com Legal Department has developed and maintains reporting guidelines for employees who wish to report violations of the Code of Conduct. These guidelines include information on making reports to the Legal Department and to an independent third party. Please see the reporting guidelines for information and instructions.
Amazon.com will not allow retaliation against an employee for reporting misconduct by others in good faith. Employees must cooperate in internal investigations of potential or alleged misconduct.
Employees who violate the Code of Conduct will be subject to disciplinary action up to and including discharge.
