If I can add, I would encourage you to have flexibility here, because there are many cases of people reporting effectively to their supervisor. I don't think they should be prevented from doing that, but I think you should recognize that there are limitations if that's their only avenue. I would also add that I think there should be an internal reporting mechanism for people. To require people to always go external, to some independent body, is not optimal in many circumstances.
