The House of Lords has voted to introduce a new duty to investigate whistleblowing concerns placing an obligation on employers to act when whistleblowers speak up.
This would mean organisations with more than 50 staff, or a turnover of more than £10 million, will have to investigate the whistleblowing concerns that are brought to them.
The amendment to the Employment Rights Bill, proposed by Protect and drafted by Lord Michael Wills (Labour) was supported by Baroness Susan Kramer (Lib Dem) and Baroness Nicky Morgan of Cotes (Conservative) and passed with a 98 majority yesterday (16 July).
Whistleblowers provide employers with a vital early warning system, and many large employers recognise the benefits they bring. By ensuring there are processes to deal with workplace wrongdoing, this duty would ensure employers have to deal with potential harm early on, rather than allowing the issues to fester. The amendment also requires the government to review the unfair dismissal test which creates too high a hurdle for whistleblowers at tribunals.
A YouGov poll* commissioned by Protect in May 2025 found that two thirds (66%) of workers want a legal duty on employers to investigate whistleblowing concerns raised by employees. Research by the Association of Fraud Examiners found that 42% of fraud cases they studied were uncovered by tips with a majority reported by employees. A legal duty on employers would help employers mitigate this risk and root out fraud within the workplace.
