For many of us, our experience in coming from the private sector, as well as in talking to people we know who work within the immigration department—in different circles in my case—would indicate that the employees who work within these departments often recognize when something is going sour at the desk next to them or in the same department. They see the first signs of fraud.
Is there any mechanism within your management structure, something that some people would term “whistle-blower” style—I don't want to use the word “legislation”—that would allow one of those employees to come forward and tell management without major repercussions within their work environment?
