Comment Integrity Hotline (Score 4, Interesting) 310
If you're working for a Fortune 500 company there likely will be some form of internal integrity hotline. I know my own corporation has one. Document your concerns and contact them. I recently had to report a concern raised about one of the major offshore contractors we use to our integrity hotline and it was actually a very good experience from my side. After submitting the issue it took a few days but an investigator from our legal department contacted me and we had a phone conversation, and then I forwarded him some additional details I had held back from the initial correspondence. I did that mostly to protect an individual from the contractor who brought the concerns to my attention.
I would make sure that the correspondence you send to your legal department includes copies of some of the email chains you have with your managers, peers, etc... raising the concerns. Be sure to specify any regulations you suspect are being violated. If the legal team determines there is concern you can bet that change will happen. If they determine otherwise, then you've done your due diligence and reported it within the means your company gives for you to report it.
