A solid sick-day email gives the dates, what’s included, and how to reach you if something can’t wait.
Calling in sick is awkward. You don’t want to overshare, but you also don’t want to leave your manager guessing. A short, clear message fixes that. It sets expectations, protects your time to rest, and keeps work moving without drama.
You’ll get ready-to-send templates, subject lines, and a quick handoff pattern you can reuse when you feel too sick to think.
What An out sick email needs
A sick email works when it answers the questions your manager and coworkers will ask right away. Keep it tight, but don’t leave gaps that force a follow-up.
State the time window
Say whether you’ll be out for a full day, part of a day, or more than one day. If you’re unsure, give a best guess and promise an update at a specific time. You can keep medical details out of it.
Say what happens to today’s work
Pick one of these paths: you’ve already handed work off, you’ll hand it off once you’re able, or tasks can wait. Managers care less about perfect phrasing and more about knowing what’s at risk.
Share a contact path for urgent items
If you can’t be reached, say so. If you can be reached, name the channel and a narrow window, like “text only” or “email after 4pm.” That protects your time and helps others choose the right route.
Match your workplace rules
Some teams want a phone call first, others want a Slack note, and many want both. If your company has a call-in rule, follow it, then send the email as the written record.

Template 1: One-day absence
Subject: Sick today
Hi [Name],
I’m out sick today and won’t be online. I’ve moved [task/project] to [person] and added notes in [doc/link location]. If anything time-sensitive comes up, please text me at [number] and I’ll respond when I’m able.

Hi [Name],
I’m not well this morning and need to take a sick day. I’ll send an update by [2pm] on whether I’ll be back tomorrow. For today, [meeting A] should run with the agenda in [location], and [deliverable B] can shift to tomorrow unless you need it sooner.
Thanks,
[Your name]

Hi [Name],
I’m out sick from [date] through [date]. I’ve shared status notes for my active items in [location] and asked [person] to handle [specific responsibility]. If you need anything, email is best and I’ll reply when I can.
Thanks,
[Your name]
Subject lines that get opened fast
Keep subject lines plain and specific.
- Sick today

How To hand off work without a long message
You can be brief and still be useful. A clean handoff usually needs three bits: where the work lives, who owns it today, and what decision is pending.
Use one line per item
- [Project]: status + next step + owner
- [Client/task]: what’s due today + where the file is + who can send it
- [Meeting]: cancel or delegate + where the agenda sits
Write notes someone can use
Add one pointer that saves time, like “latest draft is page 3.”
Protect your rest time
If you’re truly out, say you’re offline. If you can answer one thing, set a boundary. This keeps you from getting pulled into full work mode while sick.
When A sick day becomes protected leave
Most sick emails are just a heads-up. Some absences connect to formal leave rules, which can change what you need to share and when you need to share it. If you’re in the United States and your situation may qualify for leave under the Family and Medical Leave Act, the U.S. Department of Labor explains what notice needs to contain and when notice is due in its fact sheet on employee notice under FMLA.
You still don’t need to write a medical story in an email. What matters is giving enough info for your employer to understand you need time away, plus following your employer’s normal call-in steps unless something unusual blocks you from doing so.
Table 1: What To say in an out sick email by scenario
| Scenario | Include in the email | Line you can copy |
|---|---|---|
| One full day | Date, offline note, handoff or delay plan | “I’m out sick today and won’t be online.” |
| Half day | Hours you’ll miss, what you’ll still handle | “I’m out sick this morning and expect to be back after 2pm.” |
| Unsure return | Best guess, update time, handoff note | “I’ll send an update by 2pm on tomorrow.” |
| Multiple days | Date range, handoff owner, where notes live | “I’m out sick from Tue through Thu.” |
| Client-facing role | Who is the backup contact, what you’ve already sent | “[Name] can reply to any client items today.” |
| Shift work | Shift time, swap request, manager ack | “I can’t work my 3–11 shift; I’m reaching out for a swap.” |
| Remote team across time zones | Your local date, your hours, who to ping | “I’m out sick today (Tue, my local time).” |
| New job or probation period | Extra clarity on tasks, extra courtesy | “I’m out sick today; my notes are in [location].” |
Out Sick Email Template For school and training
For classes, the goal is to respect your instructor’s time while making it easy to tell you what you missed. Keep it polite, keep it short, and include what you need: today’s class, your section, and what you’ll do next.
Template 4: Student email to an instructor
Subject: Absent today from [course + section]
Hi [Instructor name],
I’m sick today and won’t be able to attend [course name] on [date]. I’ll check the LMS for notes and will catch up on any posted work. If there’s anything I should submit or check right away, please let me know.
Thanks,
[Your name]
[Course + section]
Template 5: Short note for a tutor or training session
Subject: Need to reschedule today
Hi [Name],
I’m sick and can’t make our session today at [time]. Can we move it to [two options]? I’ll confirm as soon as you pick one.
Thanks,
[Your name]
Slack, Teams, and chat versions that still sound human
Many teams want a quick chat message, then an email to your manager. Chat messages should be even shorter than email, since they sit in a fast-moving channel.
Chat message to your manager
- “Hey [Name], I’m out sick today and offline. Notes for [project] are in [place]. I’ll update you by 2pm.”
Chat message to your team channel
- “Out sick today. [Name] is handling [thing]. Please tag them for urgent items.”
Chat message for shift swap
- “I’m sick and can’t work my [time] shift. Can anyone take it? I’ve told [manager].”
Table 2: Tone tweaks by workplace style
| Workplace style | What to do | Phrase that fits |
|---|---|---|
| Formal | Use greeting, full sentences, clear sign-off | “I’m out sick today and unavailable.” |
| Casual | Short lines, still clear on timing | “I’m out sick today. Back tomorrow if I’m better.” |
| Client-heavy | Name a backup contact and where files sit | “[Name] can handle client replies until I’m back.” |
| Engineering or ops | Point to ticket links, runbooks, on-call backup | “On-call is handled by [Name]; runbook is linked in [place].” |
| Education | Reference class date, section, and next steps | “I’ll catch up via the LMS and submit work on [date].” |
Common mistakes that slow things down
Most sick emails go wrong in predictable ways. Fix these and you’ll save yourself back-and-forth.
Too much detail
You don’t owe anyone your symptoms. A simple “out sick” is enough in most workplaces. Save health details for a doctor and the formal leave process, if one applies.
No plan for meetings
If you have meetings on your calendar, say what should happen: cancel, delegate, or let it run without you. One sentence can keep five people from waiting in a call.
Vague reachability
“I’ll try to check messages” invites pings all day. If you’re offline, say it. If you can reply to one thing, set a narrow lane like “text only for urgent items.”
Forgetting the handoff location
People can’t act on “my notes are in the doc” if there are ten docs. Name the folder, the file, or the ticket number. If you can’t, pick a single place to drop a note and share that.
Small etiquette moves that earn trust
These are tiny, but they help your message land well.
- Send it early if you can, before meetings start.
- If you’re late sending it, add one line that owns it: “Sorry for the late note.”
- Thank the person stepping in for you, by name.
- When you return, send a short follow-up: “Back online today.”
Mini checklist you can paste into your notes
Next time you’re sick, you won’t want to think. Save this checklist and fill it in fast.
- Dates or hours I’ll be out
- Whether I’m offline
- Top 1–3 items that need a handoff
- Who owns each item today
- Where my notes live
- How to reach me for one urgent item, if needed
- When I’ll send an update
If your sick day relates to a contagious respiratory illness, public health guidance often recommends staying home until you’re improving. The CDC’s page on precautions when you’re sick outlines when to stay home and steps to cut spread once you start feeling better.
Use that guidance to decide when you can return, then keep your message to work focused on timing and handoffs. Your email is a work tool, not a medical report.
