Can my employer cut my pay without my agreement?

Your rate of pay is a fundamental term of your employment contract. Your employer cannot change it without your agreement. A unilateral pay cut — one imposed without your consent — is a breach of contract. It may also amount to an unlawful deduction from wages under the Employment Rights Act 1996 (s.13), which prohibits deductions from wages not authorised by statute, a relevant provision in the contract, or prior written consent.

If your employer imposes a pay cut, you have three options. First, you can agree to it (expressly or by continuing to work without protest for a significant period). Second, you can refuse to accept it in writing, continue working, and bring an unlawful deductions claim in the Employment Tribunal for the shortfall (usually within 3 months). Third, if the pay cut is severe enough to amount to a fundamental breach of contract, you may be able to resign and claim constructive dismissal — though this requires 2 years' service.

Employers sometimes attempt a lawful variation by giving notice to terminate the old contract and offering re-engagement on new (lower-pay) terms. If you do not accept, you may be dismissed — and whether that dismissal is fair depends on whether there was a sound business reason and whether the employer consulted properly. Seek advice before deciding how to respond to any proposed pay cut.
