Proposed change to terms and conditions letter
Proposes a change to contractual terms, explains why, invites discussion, and seeks written agreement.
You need to change something contractual: hours, shift pattern, place of work, a pay element, a benefit. Unless the contract has a clear flexibility clause covering exactly this, a change needs agreement. This letter opens that conversation properly. Imposing a change, or dismissing and re-engaging to force it, is now heavily restricted; take advice before going near it.
Before it goes
- You have checked the contract for a flexibility or mobility clause that already covers the change. If it does, a different, shorter letter applies.
- You can explain the business reason in plain terms and have considered alternatives.
- You have counted: if 20 or more employees might be dismissed for refusing, collective consultation rules apply.
The letter
Filling it in
- The proposal
- Exact. Hours, times, pay, place. The employee is deciding whether to agree to it; they need to know what "it" is.
- The last paragraph
- Deliberately does not threaten dismissal. Given the 2024 Code and the 2025 Act, that conversation, if it ever comes, needs advice first.
What the law says
- Contract law: a variation to contractual terms requires agreement (express or by conduct over time); unilateral imposition is a breach.
- Employment Rights Act 1996 s.4: an agreed change to the written particulars must be confirmed in writing within one month.
- Statutory Code of Practice on Dismissal and Re-engagement (in force July 2024) and the Employment Rights Act 2025: dismissal for refusing a contractual variation is restricted and in most cases automatically unfair once the relevant provisions are in force; a tribunal can also uplift compensation by 25% for failing to follow the Code. Take advice before contemplating dismissal and re-engagement.
What turns this letter into a claim
- Do not write "the change will take effect on … whether or not you agree". That is imposition, and the letter becomes the evidence.
- Do not rely on a vague flexibility clause ("such other duties as the company may require") for a major change. Courts read them narrowly.
- Do not skip consultation because the change is small. A month of proper discussion is cheaper than a claim.
Questions people ask
What if an employee refuses to agree?
Keep talking. Find out what the objection is and whether an adjustment solves it. If not, the options are to proceed with those who agree and leave the objector on their old terms, to drop the proposal, or to take legal advice on the position, because dismissal for refusing a variation is now tightly restricted and in most cases automatically unfair.
Does silence mean agreement?
Not reliably. Working under the new terms for a long period without protest can amount to agreement by conduct, but an employee who objects in writing and works "under protest" has not agreed. Get a signature.
Do I have to give anything in return?
Not legally, but agreement is easier when there is something in it for the employee. A day's holiday, a small payment, or a genuinely better pattern often settles what a bare request would not.
