Employees often have access to information on waste, fraud, abuse, corruption, or dangers to public health and safety. By reporting them, whistleblowers often prevent huge losses or danger. However, they must be sure that their identity remains completely anonymous and that it is not dangerous for them to disclose the information.
For example, an employee who knows about corruption in his organisation decides to report it. However, the person accepting the bribes is highly positioned and can not only get the whistleblower fired, but also give him a negative reputation and prevent him from finding a job in the future. Special security measures and anonymity are necessary.
