A leave embargo announcement communicates that annual leave will not be available during a defined period due to business needs. Whether it’s a Christmas shutdown, a product launch, financial year-end, or a regulatory audit, employees need clear, early notice about when they cannot take leave — and the business reason behind it.
Key Takeaways
- A leave embargo (blackout) must be reasonable, clearly communicated, and applied consistently to avoid grievances.
- UK employers can restrict leave during specific periods under the Working Time Regulations, as long as they give adequate notice and employees can still take their full statutory entitlement elsewhere.
- Australian employers must ensure the embargo is reasonable under the Fair Work Act and any applicable award or enterprise agreement.
- Announce the embargo as early as possible — ideally at the start of the leave year or at least 8-12 weeks before the blackout period.
- An embargo does not replace the need for individual leave approval — employees must still submit requests for the permitted dates.
Template 1: General Leave Embargo Announcement
Use for a standard blackout period — peak season, year-end processing, or a major project.
Subject: Leave Blackout Period — [Dates] — Important Information
Hi Team,
As part of planning for [peak season / our end-of-year processing / the [Project Name] launch], we have identified a period during which annual leave cannot be approved.
Blackout period: [Start Date] to [End Date]
Reason: [Brief business reason — e.g. "We will be processing year-end payroll and finalising annual accounts, which requires full team availability."]
During this period:
- Annual leave requests will not be approved
- Emergency leave will be handled on a case-by-case basis
- Pre-approved leave that falls within this period [will/will not] be honoured — if affected, your manager will contact you separately
Outside this period, leave continues to be available as normal. Please plan your remaining leave around these dates.
Thank you for your understanding and cooperation.
Best regards,
[Your Name]A general embargo announcement should explain the “why” — employees are more accepting of restrictions they understand. For more on structuring leave policies, see our employee leave policy template.
Template 2: Project-Specific Embargo
For a specific project launch, go-live, or critical milestone where only certain team members are affected.
Subject: Leave Embargo — [Project Name] — [Dates]
Hi Team,
With the [Project Name] go-live scheduled for [Date], we are implementing a leave embargo for the project team during the critical delivery period.
Affected team members: [Names of specific team members / departments / roles]
Embargo period: [Start Date] to [End Date]
During this period, annual leave will not be approved for affected team members. If you have existing leave booked within these dates, please speak to your manager to discuss.
Why this is necessary: The [Project Name] timeline is fixed, and we need the full team available for [testing / training / go-live support].
After the embargo, leave will return to normal from [Date]. The team will receive [recognition / time off in lieu] for the additional commitment during this period.
If you have concerns about how this affects you, please speak to [Project Manager Name].
Best regards,
[Your Name]Project-specific embargoes should be limited to the people who are genuinely needed. Blanket embargoes on the whole company for a project that only involves a specific team breed resentment.
Template 3: Financial Year-End Embargo (AU Specific)
For Australian businesses during EOFY processing.
Subject: Leave Embargo — End of Financial Year Processing
Hi Team,
As we approach the end of the financial year, we will be implementing a leave embargo for team members involved in EOFY processing.
Embargo period: [Start Date] to [End Date]
Affected roles:
- Finance and accounting team
- Payroll team
- [Other roles as needed]
During this period, annual leave requests from affected team members will not be approved. If you have pre-approved leave during this period, your manager will discuss the options with you.
For non-affected team members, leave continues as normal — but please be aware that response times from [Finance/Payroll] may be slower during this period.
We appreciate your hard work during this busy period.
Best regards,

[Your Name]Legal Considerations
UK: Under the Working Time Regulations 1998, the employer can determine when annual leave is taken. A leave embargo is legally valid as long as the employee still receives their full statutory annual leave entitlement (5.6 weeks), the employer gives adequate notice (at least twice the length of the leave being restricted), and the restriction is not discriminatory.
Australia: Under the Fair Work Act 2009, the employer can direct an employee to take annual leave if the direction is reasonable, and can refuse leave during a blackout period if there is a reasonable business ground. Consider factors like whether the employee has had a genuine opportunity to take leave outside the embargo, the length of the embargo, and the employee’s personal circumstances.
For more on related topics, see our guides on leave blackout periods and handling leave requests during peak periods.
FAQ
How long can a leave embargo last?
There is no legal limit, but best practice is 2-4 weeks. Longer embargoes should be rare and well-justified. If an embargo lasts more than a month, employees may have difficulty taking their full annual leave entitlement by year-end.
Can an employee refuse a leave embargo?
In the UK, the employer has the right to determine when leave is taken, so refusal is not an option. In Australia, the employee can challenge the direction on the grounds that it is not reasonable. The Fair Work Commission can hear disputes about unreasonable leave directions.
Do I need to include the embargo in the employment contract?
No, but the leave policy (including blackout periods) should be documented in the employee handbook or leave policy so employees know what to expect. See our employee handbook template.
What about pre-approved leave that falls within a newly announced embargo?
Honour it if possible. If you must cancel pre-approved leave, follow the process in our employer cancelling approved leave guide and offer compensation or alternatives.
Can I apply an embargo to only some employees?
Yes, as long as the distinction is based on a legitimate business reason (role, project, department). Embargoes based on protected characteristics would be discriminatory.
