2. The law
PIDA 1998 and the Employment Rights Act 1996
The main whistleblowing law in Great Britain is the Public Interest Disclosure Act 1998, usually shortened to PIDA. PIDA did not create a standalone statute you can read on its own. Instead, it inserted whistleblowing protections into an existing law, the Employment Rights Act 1996 (ERA 1996). So when lawyers talk about "protected disclosures," the detailed rules actually live in the ERA 1996.
What the law does
PIDA works by protecting the person, not by forcing the organisation to fix the problem. It does not oblige an employer to investigate, and it does not give a regulator new powers. What it does is make it unlawful to punish a worker for making a protected disclosure. If a worker is dismissed or otherwise mistreated because they blew the whistle, they can bring a claim to an employment tribunal.
The structure, in plain terms
The law works in layers:
- A disclosure of information about one of the six categories of wrongdoing, made with a reasonable belief that it is in the public interest, is a "qualifying disclosure"
- A qualifying disclosure made through an appropriate route, such as to your employer or a prescribed person, becomes a "protected disclosure"
- A worker who suffers dismissal or detriment because of a protected disclosure can seek a remedy at tribunal
A 2013 refinement
The rules were tightened by the Enterprise and Regulatory Reform Act 2013, which added the explicit public interest test covered in the next lesson. The practical effect is that purely private contractual complaints, affecting only the individual, generally fall outside whistleblowing protection, which reinforces the grievance distinction from Section 1.
You do not need to memorise section numbers. What matters is the shape: disclose information about real wrongdoing, reasonably believing it is in the public interest, through a sensible route, and the law protects you from being punished for it.
