Whistleblowers are an important part of any business, an early warning system of sorts for companies to make sure they are complying with regulations. 

A whistleblower is a worker who has reported “certain types of wrongdoing”, usually that they have seen at work, according to the UK government’s definition. The wrongdoing disclosed “must be in the public interest”, the government’s website explains, citing examples such as a criminal offence, like fraud, or a miscarriage of justice.
