Sorry, Mr. Friday, when someone only has a reasonable apprehension that wrongdoing has occurred, how can they safely explore the issues without being able to go to somebody who's not necessarily a supervisor? Then it ceases to be a protected disclosure, and that could be where the reprisals start to happen, because, “Oh, this person is digging. We have to cut them off at the knees.”
Your act does not protect it, and none of your recommendations address that point.
