A whistleblower (also written as whistle-blower or whistle blower) is a person who exposes secretive information or activity that is deemed illegal, unethical, or not correct within a private or public organization. The information of alleged wrongdoing can be classified in many ways: violation of company policy/rules, law, regulation, or threat to public interest/national security, as well as fraud, and corruption. Those who become whistleblowers can choose to bring information or allegations to surface either internally or externally. Internally, a whistleblower can bring his/her accusations to the attention of other people within the accused organization such as an immediate supervisor. Externally, a whistleblower can bring allegations to light by contacting a third party outside of an accused organization such as the media, government, law enforcement, or those who are concerned. Whistleblowers, however, take the risk of facing stiff reprisal and retaliation from those who are accused or alleged of wrongdoing.
