Being frozen out after you raise a genuine concern can be enough to justify resigning.

If your employer ignores a genuine whistleblowing concern and freezes you out afterwards, that pattern can be enough to justify resigning and claiming constructive dismissal, and your employer's failure to follow its own whistleblowing policy can increase your compensation.
- Keep a written copy of your concerns, along with a note of how your employer actually responds to them.
- If you're excluded, ignored, or frozen out after raising a concern, this can count as a breach of trust even without one single dramatic incident.
- Get advice before you resign if you're considering leaving because of how you've been treated after whistleblowing, since time limits for these claims are short.
The situation
A school business manager at an academy trust raised concerns about how the trust was being governed, culminating in a formal whistleblowing letter to the board of trustees on 10 February 2024. In a pattern that started before her letter and continued for months afterwards, she was sent a hostile, singling-out email by a colleague, excluded from two work dinners, and increasingly ignored by her line manager. The trustees said by phone that they would look into her letter but never actually investigated or followed up on what she had raised. With nothing having changed roughly two months after she wrote to the board, she resigned.

It held that being ignored and frozen out after raising a genuine, good-faith concern, combined with her employer's total failure to follow its own whistleblowing policy or investigate her concerns, amounted to a breach of trust and confidence serious enough to justify her resignation. Because the trustees had also failed to engage properly with the tribunal process, including failing to respond promptly and disclose documents, the tribunal increased her compensation by 25 per cent for breach of the ACAS Code.
