What is the difference between making a complaint and blowing the whistle?
When someone blows the whistle they are raising a concern about danger or illegality that affects others (e.g. customers, members of the public, or their employer). The person blowing the whistle is usually not directly, personally affected by the danger or illegality. Consequently, the whistleblower rarely has a personal interest in the outcome of any investigation into their concern – they are simply trying to alert others. For this reason, the whistleblower should not be expected to prove the malpractice. He or she is a messenger raising a concern so that others can address it.
