Sick Leave Email Template: Examples for Every Situation

Nobody enjoys writing a sick leave email template from scratch while feeling terrible. The good news: an effective sick leave email is one of the simplest professional messages you will ever send. It needs three things — the dates you will miss, what happens to your work while you are out, and how reachable you are. Everything else is optional.

This guide gives you ready-to-use templates for one-day, multi-day, and extended absences, plus guidance on tone and privacy so you sound professional without oversharing.

What Every Sick Leave Email Needs

Before the templates, the anatomy. Every sick leave email should contain:

1. A clear subject line. "Sick Leave — [Your Name], [Date(s)]" tells your manager everything before they even open the message.
2. The absence dates. State exactly which days you will miss. "I will be out today" is fine for a single day; give a range for longer absences.
3. Coverage arrangements. Note anything urgent: who is covering, what is postponed, or that nothing time-sensitive is pending.
4. Your availability. Say whether you will be checking messages or are fully offline. Fully offline is usually the right call when you are genuinely ill.
5. A professional close. One line is enough — no groveling required.

What it does not need: a detailed description of your symptoms, apologies repeated three times, or promises to "make up every minute." Keep it brief and factual.

Template 1: One-Day Sick Leave

The most common case. Send it as early as you can — before your workday starts if possible.

Subject: Sick Leave — [Your Name], [Date]

Hi [Manager's Name],

I'm writing to let you know I won't be able to work today, [Date], as I'm unwell. [Colleague's Name] is aware of my active tasks and can cover anything urgent. I don't expect anything time-sensitive to slip, but please let me know if something critical comes up.

I'll be offline resting today and will update you tomorrow morning on whether I'll be back.

Thanks for your understanding, [Your Name]

Notice what is missing: no diagnosis, no elaborate apology, no speculation about tomorrow beyond a promise to update. Short and complete.

Template 2: Multi-Day Sick Leave

When you expect to miss several days — a bad flu, a minor procedure with recovery time — say so upfront so your manager can plan.

Subject: Sick Leave — [Your Name], [Start Date] to [End Date]

Hi [Manager's Name],

I need to take sick leave from [Start Date] through [End Date] as I'm unwell. Here's the coverage plan:

• [Project/task]: [Colleague's Name] is covering; I've briefed them this morning.
• [Meeting on Date]: please cancel or move to next week.
• Nothing else time-sensitive is outstanding.

I'll be offline during this period to recover properly. If anything truly urgent comes up, I'm reachable by text, but I expect the coverage plan to hold.

I'll confirm my return on [End Date] and can provide a doctor's note if needed.

Best regards, [Your Name]

The coverage list is the part managers appreciate most — it turns your absence from their problem into a handled situation.

Template 3: Extended or Uncertain Leave

For longer or open-ended absences, loop in HR per your company policy and keep the email factual.

Subject: Extended Sick Leave Request — [Your Name]

Hi [Manager's Name],

I'm writing to request sick leave starting [Date]. Based on my doctor's advice, I expect to be out for approximately [timeframe], though I'll update you if that changes.

I've documented my current projects [location of handover notes] and [Colleague's Name] has agreed to be the point of contact. I'm copying [HR Contact] so we're aligned on policy and documentation — I can provide a medical certificate as required.

I'll check in with updates on [agreed cadence, e.g. weekly]. Thank you for your support.

Kind regards, [Your Name]

For extended leave, documentation and a handover note matter more than eloquence. An AI email assistant can help you draft a clear handover summary to attach, so nothing falls through the cracks while you recover.

Calling In Sick Mid-Workday: The Short Version

Sometimes illness hits halfway through the day. You do not need a full template — a brief message to your manager and any affected teammates is enough:

Hi [Manager's Name] — I'm not feeling well and need to head out for the rest of the day. [Colleague's Name] has what they need for [time-sensitive item], and I'll check messages briefly this evening if anything urgent comes up. I'll update you in the morning.

Send it, log off, and rest. Resist the urge to "quickly finish" things while sick — half-done work created in a fog usually needs redoing, and pushing through a contagious illness puts colleagues at risk too.

Sick Leave When You Work Remotely

Remote workers face a particular temptation: working through illness because "it's just opening a laptop." The standard is the same as in an office — if you are too sick to do good work, take the day. A short sick leave email still matters for remote teams because your absence affects standups, response times, and shared deadlines. Set your status to out-of-office, silence notifications, and actually rest; answering "just one quick message" has a way of becoming a full workday.

Tone Guidance: Professional, Not Dramatic

The right tone is calm and matter-of-fact. You are informing, not confessing. A few principles:

• One apology is enough. "Thanks for your understanding" covers it. Repeated apologies ("I'm SO sorry, I feel awful about this") can read as anxiety rather than professionalism.
• Don't negotiate with yourself. Phrases like "unless that's a problem" or "if it's okay" undermine a legitimate request. You are notifying, not begging permission, when you are genuinely ill.
• Match your workplace culture. A formal workplace gets "Best regards"; a casual startup gets "Thanks." The templates above lean neutral — adjust one notch toward your norm.

What Never to Overshare

Your health information is private, and most managers prefer it that way — detailed medical descriptions create awkwardness, not sympathy. "I'm unwell and unable to work" is a complete explanation for a short absence. You do not owe anyone your symptoms, your diagnosis, or your treatment plan.

The exceptions are narrow: if your absence affects workplace safety, if you need specific accommodations on return, or if company policy explicitly requires documentation (usually only beyond three to five days). In those cases, share the minimum necessary, preferably with HR rather than your whole team.

When Your Employer Asks for a Doctor's Note

Some companies require documentation for absences longer than a set threshold — often three to five consecutive days. If that applies to you, mention it proactively in your email ("I can provide a doctor's note if needed") rather than waiting to be asked. Keep the note itself between you and HR, not your direct team. And if obtaining a note is difficult — for example, your clinic has no same-week appointments — say so plainly and ask what alternative your employer accepts. Most reasonable workplaces would rather have honest communication than a forged-feeling scramble. When in doubt, a quick call to HR to clarify the requirement beats guessing.
