Whether your employer can change your contract, the Code of Practice on Dismissal and Re-engagement, and the protections due in January 2027.
Describe what has happened. The checker answers only from this guide, plus what you tell it, and says so if something is not covered.
Check My Situation →Employees in England, Wales or Scotland whose employer wants to change their contract, for example pay, hours or shifts, and has threatened to dismiss them and offer a new contract on the new terms ("fire and rehire").
Employment contracts, whether written or verbal, are legally binding agreements. Their terms cannot usually be changed by just one party. Changes will need to be agreed by both the employer and the employee, or with a trade union or other employee representatives in some circumstances.
This is called dismissal and re-engagement, or fire and rehire. Your employer should follow the government's statutory Code of Practice on Dismissal and Re-engagement.
The Code says your employer should tell you what changes they want to make, why they think the changes are needed, and what alternative options they have thought about. They should give you this information in writing before they make a final decision, listen to your views and take your feedback seriously.
If you are dismissed, it is still a dismissal, even if you are offered a new contract. With enough service, it might be unfair dismissal if there was no fair reason, the reason was not enough to justify dismissing you, or your employer did not follow a fair procedure.
You currently need at least 2 years of continuous employment to claim ordinary unfair dismissal. If your employment ends on or after 1 January 2027, you need at least 6 months.
Not yet. The Employment Rights Act 2025 will make it automatically unfair to dismiss an employee for refusing a "restricted variation", such as a change to pay, hours, shift times, time off or pensions, with a narrow exception for an employer in severe financial difficulty.
These protections are not in force yet. The government's updated timeline says they will start in January 2027. Until they start, today's rules apply.
