The government has programs and protections in place for whistleblowers with a legit issue. I don’t believe those programs and protections mean much.
Many years ago, a mentor of mine gave me some very good advice.
If you decide to become a whistleblower, your career is over.
The superiors will never trust you again, and neither will any other in the industry.
But be prepared to to stand up of you need to. Integrity is not for the cowards.
