Margaret Heffernan: Whistleblowers

Entrepreneur Margaret Heffernan challenges the negative view of whistle-blowers and argues that people who dare to speak uncomfortable truths are vital to the success of businesses and other organisations.

All too often important information is available, but acting on it is avoided because it would cause conflict. As a former CEO, she believes that a positive attitude to dissent is the key to progress.
