Online Doctor's Note for Missing Work

How employers usually handle documentation

There’s no single federal rule that governs when an employer can ask for a doctor’s note or how much sick leave you’re owed. The Department of Labor is direct about this: federal law does not require sick leave at all, paid or unpaid, so what your employer asks for after a day or two out sick comes down to its own policy, plus whatever your state or city requires. That’s worth checking in your employee handbook before you assume a note is or isn’t necessary. Some employers only ask for documentation after a certain number of consecutive sick days, while others want a note for any short-notice absence; there’s no universal rule, so the safest approach is to ask your manager or HR directly rather than guess.

A general benchmark for contagious illness

If what kept you home is a respiratory virus like a cold or the flu, the CDC’s guidance is a reasonable benchmark for when you’re ready to be around others again: your symptoms should be improving overall, and you should be fever-free for at least 24 hours without fever-reducing medication, with both true at the same time. That guidance is written for respiratory viruses specifically; other illnesses have their own timelines and their own red flags, which is why we have separate pages for things like the flu and food poisoning with more specific detail.

Signs you need care beyond a note

An absence note documents that you reported being unwell and were advised to rest; it isn’t a substitute for an exam. If you have trouble breathing, chest or abdominal pain, confusion, a fever that isn’t responding to medication, or symptoms that keep getting worse instead of better after a few days, get evaluated in person rather than waiting on an online note. The specific warning signs differ by illness. If your absence is tied to a specific condition like the flu, food poisoning, or a migraine, our pages for those reasons list the red flags that apply to that condition in more detail.

What to tell your employer

Most workplaces just need to know you were out and for how long. The note can confirm you were advised to rest for the dates given without naming a specific illness, if you’d rather keep that private. If your employer wants to confirm the note is genuine, that only happens with your permission, since a doctor can’t share your health information with anyone else without your consent. It’s also worth keeping a copy of the note and noting the date you sent it to your employer, in case there’s ever a question later about when you reported the absence.
