Do you feel that using a third party could potentially better protect the employee or department that is subject to an investigation?
I'll just give you a quick example. If you're investigating a particular department where the whistle-blower, the employee, finds himself or herself, they will be in a specific department, a specific branch, and if I were the manager, it would be fairly easy to identify who that person could be. However, using a third party, perhaps using access to information, could potentially hide better the identity of the employee.
Do you feel that this could be useful?
