A recent OSHA whistleblower investigation discovered the National Railroad Passenger Corp., also known as Amtrak, reprimanded a supervisor in its inspector general's office when he raised safety concerns.

In early to mid-2010, the worker, a supervisory special agent, was in the process of investigating an Amtrak contractor for fraud and was testing concrete at Amtrak tunnel projects. While at the worksite, the employee discovered unsafe conditions resulting from work performed by the contractor and raised concerns.
