What to Say When Calling in Sick to Work: Examples
If you want to know what to say when calling in sick to work, examples help more than theory, and the pattern behind them is short: notify early, say you cannot work, give a return estimate, and stop. Most people over-explain, and the over-explaining is what creates problems rather than the absence itself.
Below you will find ready-to-use scripts for calls, texts, and emails, what your employer is genuinely entitled to ask, how much detail you owe them, and the specific mistakes that turn a routine sick day into an awkward conversation.
What Should You Say When Calling in Sick to Work?
Four elements, in this order: that you are unwell and cannot work, when you expect to return, what is urgent today, and how you can be reached. Everything past that is optional.
Here is the basic version, suitable for a call or a message to a manager:
Hi [Name], I’m unwell today and won’t be able to work. I expect to be back tomorrow, and I’ll let you know by this evening if that changes. The [specific task] is ready to hand over if it can’t wait, and [colleague] has the file. I’ll keep my phone on for anything urgent.
That covers everything a manager needs to plan the day. It does not name a symptom, which is deliberate. From what we’ve seen, the messages that go badly are almost never too short. They are the ones that pile on detail, because detail invites follow-up questions and can read as though you are working to be believed.
Adjust the length to your workplace rather than to how ill you feel. A short text suits a team that runs on Slack. A phone call suits a manager who expects one, and a rota-based job where somebody has to fill your shift.
Calling in Sick to Work: Examples for Common Situations
These calling in sick to work examples cover the situations people ask about most, though the four elements stay the same in each. Use these as starting points and match them to your own voice.
Short notice, same morning
Hi [Name], I woke up unwell and won’t be in today. I’m hoping to be back tomorrow. Nothing on my list is time-critical except [task], which I’ve flagged to [colleague]. Sorry for the short notice.
You need more than one day
Hi [Name], I’m still unwell and won’t be able to work today either. I’ll update you tomorrow morning with a clearer sense of timing. If this runs past [day], I’ll let you know so we can plan cover properly.
Mental health day
Hi [Name], I’m not well today and won’t be able to work. I plan to be back tomorrow and will confirm this evening.
The wording is deliberately identical to a physical illness, because in most workplaces you are under no obligation to distinguish. If you have a good relationship with your manager and want to be direct, that is your call to make, not an expectation to meet.
Caring for a sick child or relative
Hi [Name], my [child/relative] is unwell and I need to stay home with them today. I’ll be reachable by message if something urgent comes up, and I expect to be back tomorrow.
Contagious illness, employer needs to know
Hi [Name], I’ve come down with something contagious and won’t be in. Flagging it because I was in the office [day] and sat near [team]. I’ll follow whatever the policy says about returning.
Email version, for a formal workplace
Subject line: Sick leave, [date]
Hi [Name], I’m unwell and unable to work today. I expect to return on [date] and will update you if that changes. [Colleague] can cover [task] in the meantime. Please let me know if you need anything from me. Best, [Your name]
What Is Your Employer Allowed to Ask?
More than most articles on this topic suggest, and it is worth knowing accurately rather than comfortably. The widely repeated claim that an employer can never ask why you are off is not correct.
The U.S. Equal Employment Opportunity Commission states in its enforcement guidance: “An employer is entitled to know why an employee is requesting sick leave. An employer, therefore, may ask an employee to justify his/her use of sick leave by providing a doctor’s note or other explanation, as long as it has a policy or practice of requiring all employees, with and without disabilities, to do so.” That passage appears in the EEOC’s guidance on disability-related inquiries and medical examinations of employees.
Read the condition at the end carefully, because it is the protection. The requirement has to apply to everyone. An employer who demands a doctor’s note from one person and not from colleagues in the same situation has a problem, and separately, the ADA restricts disability-related inquiries unless they are job-related and consistent with business necessity.
Practically, this means “I’m unwell and unable to work” is an explanation. A diagnosis is a different thing, and the gap between those two is where your discretion lives. The Job Accommodation Network’s material on disability disclosure is a useful reference if a longer-term condition is involved.
What If the Absence Is Longer or Recurring?
Then federal leave rules may apply, and the notice requirements are more specific. This is where knowing one regulation genuinely helps.
Under the Family and Medical Leave Act, covered employers must provide eligible employees with up to 12 weeks of unpaid, job-protected leave for certain medical situations. There is no federal requirement for paid sick leave, a point the Department of Labor states plainly, so paid time off depends on your employer’s policy and on state or city law.
The notice rules for unforeseeable leave sit in 29 CFR 825.303, and three details are worth knowing:
- Timing. You must give notice “as soon as practicable,” which generally means within your employer’s usual notice requirements for that kind of leave.
- Someone else can call. The regulation allows notice from a spokesperson such as a spouse or adult family member if you are unable to do it personally. It gives the example of a parent in an emergency room with a child, who is not expected to leave the child to report the absence.
- You need not say “FMLA.” The text states that when seeking leave for the first time for an FMLA-qualifying reason, “the employee need not expressly assert rights under the FMLA or even mention the FMLA.” You do have to give enough information for the employer to work out that it may apply, and for a repeat absence previously covered, you must reference the qualifying reason.
One thing most guides miss is that first point about the spokesperson. People genuinely worry about being penalized for not calling personally during an emergency, and for FMLA-qualifying leave the regulation anticipates exactly that.
What Should You Avoid Saying?
Anything that invites doubt, and anything you would not want repeated. A sick day is routine. Most of the friction comes from wording, not from being off.
A common mistake worth avoiding: the elaborate account. “I was up all night, I think it was the chicken, my temperature was 38.4 at 6am” reads as someone building a case. Compare it to “I’m unwell and won’t be able to work today.” The second is more credible precisely because it is not trying to convince anyone. We have seen the long version prompt follow-up questions that the short version never gets.
If your workplace runs on written communication, our guide to politely following up on an email with no response covers the same principle of keeping a short message effective.
Three more to skip. Do not apologize repeatedly, since one brief sorry is plenty and more suggests you did something wrong. Do not promise work you will not do, because “I’ll check emails through the day” sets an expectation you will break while ill. And do not post about your day out while off sick, which is a preventable problem that managers hear about from colleagues rather than from social media directly.
After looking at how these messages land, we prefer sending a brief written note followed by availability for a call, rather than a long message that answers questions nobody asked. It respects a manager’s morning and leaves room for them to ask if they need more.
How Do You Handle the Return?
Follow up briefly, confirm the handover, and let it go. The day back is where a well-handled absence gets undone by awkwardness.
- Check your employer’s notification policy before you need it. Many have a specific person, method, and deadline, and following it removes most of the risk.
- Send the message as early as the policy requires. Timing matters more than wording to whoever is arranging cover.
- Keep a written record. A text or email creates a timestamp, which protects you if the absence is ever questioned.
- Update if plans change. A short note saying you need another day is far better than silence.
- Get a doctor’s note if your policy requires one. Check the threshold, since many kick in after two or three consecutive days.
- On your return, confirm the handover and move on. No re-explaining, no proving how ill you were.
Workplaces that handle absence badly usually have a wider communication problem, which our guide to business communication solutions addresses.
In practice, this looks like two short messages and a normal day back. If you manage a team and find sick days are a recurring source of tension, our piece on improving team productivity without burning out your employees covers the conditions that drive it.
Frequently Asked Questions
Do I have to tell my employer what is wrong with me?
You have to give a reason for the leave, but not necessarily a diagnosis. The EEOC says an employer is entitled to know why you are requesting sick leave and may ask for a doctor’s note, provided it requires the same of all employees. “I’m unwell and unable to work” is an explanation; your specific condition usually is not required.
Is it better to call, text, or email?
Follow whatever your employer’s policy specifies, and default to the channel your manager normally uses. A written message has the advantage of creating a record with a timestamp, which is worth having if the absence is ever disputed.
Can I take a sick day for mental health?
In most workplaces, yes, and the wording can be identical to any other illness. Whether you name it is your decision rather than an obligation. Check your employer’s policy, since some define sick leave broadly and others do not.
How much notice do I have to give?
Whatever your employer’s usual policy requires, which is often a set time before your shift starts. For FMLA-qualifying leave that is unforeseeable, the regulation requires notice “as soon as practicable,” generally within those same customary requirements.
Can someone else call in for me?
For FMLA-qualifying leave, yes. The regulation explicitly allows notice from a spokesperson such as a spouse or adult family member when you cannot do it personally. For ordinary sick leave it depends on your employer’s policy, so check before you need it.
Can my employer require a doctor’s note?
Generally yes, if it applies the requirement consistently to all employees rather than singling people out. Many policies only require one after a set number of consecutive days, so check where that threshold sits in your handbook.
Am I entitled to paid sick leave?
That depends entirely on your employer and where you work. There is no federal requirement for paid sick leave in the United States, though FMLA provides unpaid job-protected leave for eligible employees at covered employers, and many states and cities have their own paid sick leave laws.
Putting These Calling in Sick Examples to Use
Across all of these what to say when calling in sick to work examples, the principle is the same: say you cannot work, say when you expect to be back, hand over anything urgent, and resist the urge to justify yourself. Your employer can ask why you are off, and “I’m unwell” answers that.
Look up your workplace’s notification policy this week, while you are healthy, and note who to contact and by when. Having that answer before you need it removes the only part of a sick day that is genuinely stressful.
