What to Say When Calling In Sick to Work

Last updated: March 19, 2026

Quick examples

Whether you're calling in sick, calling off work, or calling out — here are the go-to lines:

• Short and simple: "I'm not feeling well and won't be in today."
• With a timeline: "I'm sick today. I'll let you know about tomorrow by tonight."
• Multiple days: "I've been sick since yesterday and need another day. Hoping to be back Thursday."

That's the gist. For full scripts and what to do when your boss pushes back, keep reading.

Why this call feels hard

Even when you're genuinely sick, calling in feels loaded — there's the guilt of leaving your team short-staffed, the worry that your boss won't believe you, and the weird pressure to sound sick enough on the phone. A 2024 survey found that 42% of workers who call in sick admit to rehearsing what they'll say beforehand (Bankrate Workforce Survey). You end up rehearsing a one-minute call for twenty minutes. Here's the thing: you don't owe anyone a performance. Keep it short, keep it simple, and move on.

Before you call

• Know your company's call-out policy — some require a phone call, others accept texts or emails. Check your employee handbook or HR portal.
• Know who to contact — usually your direct supervisor. Some companies also want you to notify HR or call a specific number.
• Check your PTO/sick time balance — know whether this is paid or unpaid so there are no surprises.
• Call as early as possible — before your shift starts. The earlier you call, the more time your team has to adjust.

Script: Basic sick day

That's it. This works whether you're calling in sick, calling off, or calling out — the script is the same. You don't need to say what's wrong. "Not feeling well" covers everything from a cold to a migraine to food poisoning. If they ask for details, a vague "stomach thing" or "bad headache" is plenty.

Script: Multiple days

If you're out for more than 2-3 days, some employers may ask for a doctor's note. That's usually within their rights, but they still can't demand a specific diagnosis.

Script: Mental health day

You do not need to say "mental health day." Sick is sick. If your workplace culture is supportive of mental health, you can be more open — but you're never obligated to disclose.

If they push back

• Stay calm and firm. "I understand it's not ideal timing, but I'm not able to work today."
• You don't owe medical details. If pressed, say: "I'd rather not go into specifics, but I'm not well enough to work."
• Know your rights. If you have accrued sick time, you're entitled to use it. As of 2026, 15 states plus Washington D.C. mandate paid sick leave, and over 30 cities have local ordinances (National Partnership for Women & Families).
• Document it. Follow up your call with a brief email or text: "Per our conversation, I'm taking a sick day today, [date]."

Tips

• Call, don't text (unless your manager prefers text). A phone call shows respect. It also avoids the anxiety of waiting for a text reply.
• Don't over-explain. The more details you give, the more it sounds like you're justifying yourself. Short and direct is more believable and more professional.
• Offer a handoff, not an apology tour. Instead of apologizing five times, ask: "Is there anything time-sensitive I should pass to someone?" That's more helpful than guilt.
