When you sign your letter of offer, you have the code, you sign the code, you take the training. If you come across wrongdoing, I think it is an employee's duty, if you like, to tell somebody. If they are not comfortable internally, as I said, they have the external commissioner to whom they could disclose as well.
Whether it's loyalty or.... I don't know why they put it in the preamble, but I'm saying that as a public servant who has signed the code of ethics and values and takes it to heart and works in the federal public service, I would think most if not all people would say it's their duty to report wrongdoing if they see it.
