Our investigation concludes that not enough whistleblowers are being trained in England and that some members of the public are even going abroad in cases of so-called "whistleblower tourism".
And those whistleblowers who do have jobs are working an average of 80 hours a week as the demand for them to appear on talk shows and phone-ins grows.
One pensioner from Norwich told us: "My husband was on a trolley and was crying out for a nurse, saying he was desperate for a whistleblower. But the ward sister just said ha, join the queue.
"In the end I had to bring in a whistleblower from home. It's disgusting."
