Certain distinctions are in order.
Sometimes, in certain situations, disclosures by whistle-blowers are necessary. However, the context of our work at the Canada Revenue Agency also needs to be taken into account. Obviously, we are a prime target because of the huge amount of personal, financial and sensitive information in our possession. We have to manage this information very carefully. We ensure that employees have no more access to it than is necessary. This demands constant checks. The fact remains they owe a duty of loyalty to the government and to the agency. It's important to remind agency employees that they have responsibilities and must live up to them.
As for the other matter you mentioned, it's important to keep in mind that employees can always express their concerns or dissatisfaction within the agency, either to their supervisor or to someone higher up the hierarchy. They can also contact the Office of the Public Sector Integrity Commissioner of Canada or other resources outside the agency.
Furthermore, I must say that employees who blow the whistle on situations they consider unacceptable may not always be aware of all the efforts the agency is making to correct the very same situation. The agency has nearly 60,000 employees. Obviously, the teams working on fraud scheme issues don't disclose all the details of what they're doing at end-of-week team meetings.
In my opinion, these people have been taken seriously and work is being done, but the agency's efforts to combat fraud schemes aren't being broadcast. We don't want to give ideas to people unfamiliar with them. Communication is where some things fall through the cracks.
