The Public Interest Disclosure Act 1998 (PIDA) makes it unlawful to subject a worker to negative treatment or to dismiss them because they have raised a whistleblowing concern. Raising a whistleblowing concern is also known as a making a ‘protected disclosure’ in law. Whistleblowing rights under PIDA are day one rights. This means that the worker does not need the same two years’ service that is needed for other employment rights. The Act protects most workers in the public, private and voluntary sectors. The Act does not apply to genuinely self-employed professionals (other than in the NHS), voluntary workers (including charity trustees and charity volunteers) or the intelligence services.
