Half-day leave requests are simpler than full-day requests, but they still need structure. Your manager needs to know which half of the day you need, when you will be available, and whether anything urgent needs covering. The templates below handle morning-off, afternoon-off, and appointment scenarios — with no unnecessary detail.

Key Takeaways

  • A half-day leave email should specify which half (morning or afternoon), your available hours, and any urgent coverage you have arranged.
  • Most employers treat half-day leave as half of your daily leave entitlement — 0.5 days deducted from your annual or personal leave balance.
  • UK employees do not have a statutory right to half-day leave, but most employers allow it as a policy matter.
  • Australian employees can take personal/carer’s leave in increments of less than a full day under the Fair Work Act.
  • Sending the email at least one day before (for planned leave) or as early as possible on the day (for unplanned absence) is more important than the wording.

Template 1: Morning Off (Planned)

Use this when you have a morning appointment or commitment and will be in the office by early afternoon.

Subject: Half-Day Leave (AM) — [Your Name], [Date]

Hi [Manager],

I need to take the morning off on [Date] for a personal appointment. I'll be in the office by [time — e.g., 1:00 PM] and available for the afternoon standup.

I've cleared my morning calendar and [Colleague] can cover the [Meeting] at [time] if needed.

Thanks,
[Your Name]

Template 2: Afternoon Off (Planned)

Use this when you have an afternoon commitment — a school event, appointment, or personal errand.

Subject: Half-Day Leave (PM) — [Your Name], [Date]

Hi [Manager],

I'd like to leave early on [Date] at [time — e.g., 1:00 PM] for a personal commitment. I'll be online and available in the morning.

I've completed my morning deliverables and nothing urgent is pending for the afternoon. [Colleague] knows where to find me if anything comes up.

Thanks,
[Your Name]

Template 3: Medical Appointment (Short Notice)

When you get a last-minute appointment slot, you may not have much notice. Acknowledge the timing and offer a plan.

Subject: Half-Day Leave — [Date] (Medical Appointment)

Hi [Manager],

I've managed to get a medical appointment on [Date] at [time] and need to take the [morning/afternoon] off to attend. I expect to be back by [time].

I'll make sure [Task] is handed over before I go and will catch up on anything I miss.

Thanks,
[Your Name]

Template 4: Half-Day for Childcare Emergency

When your usual childcare falls through and you need to collect your child or arrange alternatives.

Subject: Half-Day Leave — [Date] (Childcare)

Hi [Manager],

My childcare arrangement fell through this morning and I need to leave early / arrive late today. I'll be in the office by [time] once I've sorted it out.

I've asked [Colleague] to cover the [Meeting] at [time]. I'll be reachable by phone throughout.

Thanks,
[Your Name]

If you are interviewing for an internal role or professional opportunity, you do not need to disclose the reason — “personal appointment” is sufficient.

Subject: Half-Day Leave — [Date]

Hi [Manager],

I need to take [morning/afternoon] off on [Date] for a personal appointment. I'll be available in the [other half] of the day and reachable by phone if needed.

Thanks,
[Your Name]

Template 6: Recurring Half-Day (Weekly Commitment)

If you have a recurring commitment — weekly physiotherapy, regular school pickup, ongoing treatment — discuss it with your manager once and then send a standing email each week as a reminder.

Subject: Half-Day Leave (PM) — [Date]

Hi [Manager],

Just a reminder I'll be leaving at [time] on [Date] for my regular [appointment/commitment]. Everything urgent is covered.

Thanks,
[Your Name]

How Half-Day Leave Works Across Countries

Country Half-Day Entitlement Key Rule
UK Depends on employer policy No statutory requirement for half-day leave. Most employers allow it by policy. Working Time Regulations 1998 leave the minimum unit of leave at the employer’s discretion.
US Depends on employer policy No federal requirement. Most employers allow half-day PTO accrual. Some states (CA, NY) allow sick leave in hourly increments.
AU Yes — sub-day increments allowed Fair Work Act s.92 — personal/carer’s leave can be taken in increments of less than a full day if the award or agreement allows it.
NZ Depends on employer policy Holidays Act 2003 — sick leave is in full-day units, but annual leave can be by agreement.

When to Send a Half-Day Leave Email

Situation When to Send Notice Period
Planned appointment At least 1 day before 1+ day
Medical appointment (short notice) As soon as you know the slot Same day is fine
Childcare emergency As early as possible on the day None required
Recurring commitment Once for the standing arrangement; reminder each week 1 day
Personal errand At least 1 day before 1+ day

Etiquette Tips for Half-Day Leave

  • Do not over-explain. “Personal appointment” or “personal commitment” is sufficient. You do not owe your manager a reason.
  • Cover your meetings. Before you send the email, check your calendar and offer coverage for anything in the half you will miss.
  • Be specific about the half. “I need the morning off” is clearer than “I need some time off today.”
  • Stick to the agreed time. If you said you will be back by 1:00 PM, be back by 1:00 PM. Reliability on half-days builds trust for future requests.
  • Do not make it a habit. If you need recurring half-days, discuss a formal flexible arrangement with your manager or HR.

Frequently Asked Questions

Does a half-day count as a full day of leave?

It depends on your employer’s policy. Many employers deduct 0.5 days from your annual leave balance for a half-day. Some employers have a minimum unit of one day. Check your employee handbook or ask HR.

Can my employer refuse a half-day leave request?

Yes. The same rules that apply to full-day leave apply to half-day requests. Employers can refuse for operational reasons. However, refusing every half-day request while approving full-day requests could raise fairness concerns.

Can I take half-day sick leave?

Yes. If you are unwell for part of the day, most employers allow you to take a half-day of sick leave rather than a full day. You may need to provide a fit note (UK) or medical documentation depending on your employer’s policy.

How do I request half-day leave if I work part-time?

The same process applies. State which hours you need off and when you will be available. Your leave entitlement is typically pro-rated based on your part-time hours.

Can I use annual leave for a half-day?

Yes. Annual leave can generally be taken in any increment your employer allows — full days, half days, or even hours, depending on policy. Check with HR about the minimum unit of leave your employer recognises.
