Leniency Program for Individuals and Corporations Involved in Criminal Antitrust Activity
Individuals or companies who (a) believe they may have been involved in criminal antitrust violations and (b) cooperate with the Antitrust Division can avoid criminal conviction, fines, and prison sentences if they meet the conditions of the Division’s Leniency Program. More information about the Division’s Leniency Program is available on the Leniency Program page.
Whistleblower Protections for Criminal Antitrust Activity
Whistleblower protections may apply if you (1) know of an antitrust crime; (2) are not participating in the antitrust crime; and (3) report an antitrust crime or assist a federal government investigation.
The Criminal Antitrust Anti-Retaliation Act of 2019 (CAARA) prohibits employers from retaliating against workers who report potential antitrust crimes or assist a federal government investigation.
If you believe you have suffered retaliation at work because you reported a potential antitrust crime or assisted with a federal government investigation of antitrust violations, you may file a retaliation complaint with the Occupational Safety and Health Administration (OSHA). You can learn more about filing an antitrust whistleblower complaint with OSHA at www.whistleblowers.gov.
