How to Text Your Boss You're Sick -- 8 Templates That Work

It's 6:30 AM. You feel terrible. You know you can't go to work. And now you have to text your boss -- which somehow feels harder than the actual illness.

You've been staring at your phone for ten minutes. "Hi, I'm not feeling well" sounds too vague. "I have a stomach bug" sounds too graphic. "I won't be in today" sounds too blunt. "I'm so sorry but I think I might be coming down with something" sounds like you're asking for permission. Classic overthinking a text spiral.

You're sick. This should be simple. And yet here you are, rewriting a text to your boss while your head is pounding.

Let me make this fast so you can go back to bed.

The Template That Works Every Time

"Hi [name], I'm not feeling well today and won't be able to come in. I'll keep you posted if anything urgent needs coverage. Sorry for the short notice."

That's it. Send it. Go back to sleep.

It hits every note: what's happening (sick), what it means for them (you won't be there), what you'll do about it (stay available for urgent items), and a brief acknowledgment that you know it's inconvenient.

You don't need to specify your symptoms. You don't need a doctor's note in the text. You don't need to apologize three times. You need to communicate clearly and then take care of yourself.

Variations by Situation

You're Calling In for a Mental Health Day

"Hi [name], I'm not feeling well and need to take the day. I'll be back tomorrow and can catch up on anything I miss."

You don't owe anyone a diagnosis. "Not feeling well" covers physical and mental health equally. If your workplace is one where you feel comfortable being more specific, that's your call. But you're never required to explain what kind of "not well" you are.

You Woke Up With Food Poisoning or a Stomach Thing

"Hi [name], dealing with a stomach issue this morning and need to stay home. I'll let you know if I'm able to hop on for anything later."

Short, professional, communicates the general category without graphic detail. Nobody needs to know specifics.

You're Sick but Could Maybe Work Remote

"Hi [name], I'm under the weather but I think I can work from home today if that works. I may be a bit slower than usual. Let me know if you'd rather I just take the full day."

This shows effort and flexibility while being honest that you're not at 100%. The "let me know if you'd rather I just take the full day" line is important -- it gives your boss permission to tell you to rest, which many bosses want to say but won't unless you open the door.

You Need Multiple Days

"Hi [name], I came down with something and I think I'll need a couple of days to recover. I'll keep you updated and plan to be back by [day]. Let me know if there's anything urgent I should hand off."

Proactive about timeline and coverage. Most bosses are far more annoyed by daily "still sick" updates than by one message that sets expectations upfront.

It's an Emergency or You're in the Hospital

"Hi [name], I'm dealing with a medical situation and won't be in today. I'll update you when I can. [Coworker name] has context on my current projects if anything is urgent."

When it's serious, be brief and delegate. Your boss will understand. If they don't, that's a them problem.

Timing

Text as early as you can. If you wake up at 6 AM knowing you can't go in, send the text at 6. Don't wait until 8:55 hoping you'll feel better. Early notification gives your boss time to adjust the day's plans.

If you realize mid-morning that you're getting worse and need to leave, don't tough it out: "Hey, I've been trying to push through but I'm getting worse. I need to head home. I've wrapped up [task] and [coworker] knows where things stand."

What Not to Do

Don't over-apologize. "I'm SO sorry, I feel terrible about this, I know the timing is awful, I really wish I could come in" turns a sick day into an emotional performance. One "sorry" is sufficient. You're sick, not committing a crime.

Don't ask for permission. "Would it be okay if I stayed home?" frames a health need as a request. You're informing, not asking. "I won't be able to come in" is a statement. "Could I possibly not come in?" is an invitation for them to say no. (The same assertive-but-respectful approach applies to all professional texting with your boss.)

Don't provide a novel. Your boss doesn't need your symptoms, your temperature, your medication list, or a play-by-play of your night. Brief is professional. Detailed is uncomfortable for everyone.

Don't text at 8:59 AM. Late notification signals "I didn't want to deal with this." Early notification signals "I respect your time."

Don't promise to work from bed unless you mean it. Offering to check emails and then going silent for eight hours is worse than just taking the day. If you're taking a sick day, take it fully.

The "Are They Judging Me" Fear

Most people who stress about sick-day texts are worried their boss thinks they're faking it. Let me reframe that.

If you've been reliable and present, one sick day does not make you look flaky. If your boss assumes the worst based on a single absence, that's a management problem, not a you problem.

And if you're taking a mental health day and feeling guilty about it -- your brain is part of your body. Mental health days are health days. You don't need to justify needing rest. If the guilt is building into a full shame spiral over unread messages, that's even more reason to take the day. Sick days, apology texts, boundary-setting -- these are all beyond-dating awkward texts that deserve as much attention as your DMs.

When You Come Back

The day you return, a quick message goes a long way: "Thanks for being understanding about yesterday. I'm feeling better and catching up on everything now."

That's it. Don't over-explain. Don't bring it up again. Just move forward.

When You Can't Find the Right Words

If you're lying in bed at 6 AM, brain foggy, trying to compose a professional text to your boss and nothing sounds right -- open Vervo, screenshot your last work conversation, and let it draft something for you. The direct tone is usually perfect for professional communication: clear, respectful, no wasted words.

Then put your phone down and rest. The text was never the hard part. Giving yourself permission to take care of yourself was.
