United Kingdom: Whistleblowing

Each month we pull together the employment law updates that matter most to HR professionals and in-house lawyers, in plain English.

Employment Tribunal claims have surged by 54% in Q3 2025 compared to the previous year, driven by increases in whistleblowing and discrimination cases, as well as AI-enabled claim preparation by unrepresented parties. With the Employment Rights Act 2025 provisions yet to take full effect and no significant investment in tribunal resources, the system faces mounting delays and cancellations that threaten workers' ability to enforce their rights.

Workers who "blow the whistle" on their employers have the right not to be dismissed or otherwise penalised as a result.
