Cancelling an employee’s approved annual leave carries legal and relationship risk. Under UK law, employers can cancel approved leave — but only if they give notice equal to the length of the leave requested and have a genuine business reason. Doing it badly can lead to constructive dismissal claims, grievance procedures, and significant damage to trust.
Key Takeaways
- Under the Working Time Regulations 1998, an employer can refuse or cancel annual leave by giving notice equal to the duration of the leave.
- You must have a genuine business reason — insufficient cover due to unexpected circumstances is the most common valid ground.
- The employee is entitled to alternative dates for the cancelled leave.
- Compensation is not legally required but is strongly recommended as a goodwill gesture.
- Cancelling leave for statutory reasons (maternity, parental, carers, bereavement) is not permitted.
- Always apologise — even if the business reason is sound.
Template 1: Cancellation With Full Notice (Before Leave Starts)
Use this when you have enough notice (equal to the leave duration) and the employee has not yet started their leave.
Subject: Important — Change to Approved Annual Leave — [Dates]
Dear [Employee Name],
I'm sorry to write with difficult news. Due to [unforeseen circumstances / a critical project deadline / unexpected staffing changes], I need to cancel the annual leave I approved for [Start Date] to [End Date].
I understand how disappointing this is, especially if you have made plans. I want to help you reschedule as quickly as possible.
Please let me know which of the following alternative dates work best for you:
- [Alternative date range 1]
- [Alternative date range 2]
- [Alternative date range 3]
To make up for this disruption, I am [happy to approve the alternative dates you choose / offering [X] as a gesture of goodwill].
I'm very sorry for the change and appreciate your understanding.
Best regards,
[Your Name]The apology is not an admission of liability — it’s a recognition that you are inconveniencing the employee. A goodwill gesture (an extra day off, a lunch, a small voucher) goes a long way.
Template 2: Cancellation During Leave (Recall)
In rare circumstances, you may need to recall an employee from leave that has already started. This carries significantly higher risk.
Subject: Urgent — Request to Return From Annual Leave
Dear [Employee Name],
I hope you're enjoying your time off. I'm writing to share some difficult news.
Due to [extreme circumstances — e.g. a critical system outage, a regulatory deadline, or a team emergency], I need to ask whether you would consider returning to work early from your leave.
I understand this is a significant request, and I want to be clear: this is a request, not a requirement. If you are unable to return, your leave continues as planned with no consequences.
If you are able to return, I propose the following:
- You would return on [Date]
- The unused portion of your leave ([X] days) would be reinstated for future use
- You would receive [additional compensation / time off in lieu] as compensation
Please let me know your decision. I completely understand if you are unable to help.
Best regards,
[Your Name]Recalling an employee from leave that has already started should be a request, not a demand. The employee should face no penalty for declining. If they agree, compensation is essential.
Template 3: Post-Cancellation Confirmation (With Reinstated Leave)
After discussions, confirm the new arrangement in writing.
Subject: Confirmation — Revised Leave Arrangement
Dear [Employee Name],
Following our conversation, I'm writing to confirm the revised arrangements for your cancelled leave.
Cancelled period: [Original Start Date] to [Original End Date]
Reason: [Brief business reason]
New arrangement:
- Reinstated leave: [New Start Date] to [New End Date]
- [If applicable:] Compensation: [one additional day of leave / overtime payment / other gesture]
Your leave on the original dates has been removed from the system and replaced with the new dates above.
Please confirm that this is acceptable. If you have any concerns, I'd be happy to discuss them.
Thank you for your flexibility.
Best regards,
[Your Name]Template 4: Cancellation Refused — Grievance Response
If the employee raises a formal grievance about the cancellation, respond in writing.
Subject: Response to Grievance — Cancellation of Approved Leave
Dear [Employee Name],
Thank you for your grievance dated [Date] regarding the cancellation of your annual leave from [Start Date] to [End Date].
I understand this has caused you inconvenience and frustration, and I take your concerns seriously.
After reviewing the circumstances, I confirm that the decision to cancel your leave was based on [business reason], which I considered to be a genuine operational need. The cancellation was made with [X] days' notice, which meets the requirements of the Working Time Regulations 1998.
To address your concerns, I confirm the following:
- Your leave has been reinstated for [Alternative Dates]
- You will receive [compensation/goodwill gesture]
- [Any other agreed resolution]
I am sorry for the disruption this has caused. If you remain dissatisfied, you may escalate this grievance through [next step in the grievance procedure].
Yours sincerely,
[Your Name]Legal Risks
Under the Working Time Regulations 1998, an employer can require an employee to take annual leave on specific dates, and can refuse or cancel leave by giving notice equal to the length of the leave. However, the right to cancel is not absolute:
- The reason must be genuine and operational — cancelling leave to punish an employee or in response to a protected act (e.g. requesting flexible working) could be unlawful.
- The employee must still receive their full statutory annual leave entitlement — the cancelled leave must be offered on alternative dates.
- Statutory leave (maternity, paternity, adoption, shared parental, parental, carers, bereavement, time off for dependants) cannot be cancelled — these are separate legal rights, not annual leave.
If the employee has already made non-refundable bookings (flights, hotels, event tickets), the risk of a claim increases. While the employer is not strictly liable for these costs, an Employment Tribunal may view the failure to compensate as unreasonable.
In extreme cases, cancelling leave unreasonably could amount to a constructive dismissal if the employee resigns in response. The employee would need to show that the cancellation was a fundamental breach of the implied term of trust and confidence.
Before cancelling approved leave, ask yourself:
- Is there a genuine business emergency, or can we manage without them?
- Have I considered asking for volunteers or rearranging cover differently?
- Have I given the maximum possible notice?
- Can I offer the employee something meaningful in return?
FAQ
How much notice must an employer give when cancelling leave?
Notice equal to the duration of the leave. For a 5-day leave request, at least 5 days’ notice. For a 10-day leave, at least 10 days’ notice. This applies even if the leave was approved months ago.
Can I cancel leave because of a staff shortage?
Yes, if the shortage is genuine and unexpected. A foreseeable shortage (e.g. summer holiday season) is not a valid reason to cancel leave that was approved in advance — you should have planned for it.
Do I have to compensate the employee for cancelled leave?
There is no legal requirement to compensate for cancelled annual leave (for the cancellation itself — the leave must be offered on alternative dates). However, if the employee has incurred financial losses (non-refundable bookings), best practice is to reimburse or compensate. Failure to do so may fuel a grievance or trust and confidence claim.
Can an employee refuse the cancellation?
The employer has the legal right to cancel with proper notice, but the employee can raise a grievance or, in extreme cases, claim constructive dismissal if the cancellation is handled unreasonably. It is always better to negotiate than to impose.
What about cancelling leave for casual or zero-hours workers?
The Working Time Regulations still apply. Casual and zero-hours workers accrue annual leave in the same way and have the same rights regarding notice of cancellation. However, the practical impact may differ given their variable working patterns.
