Your US employer can generally require a doctor’s note for any sick day — but several states limit when and how they can demand one. The balance between verifying legitimate absence and respecting employees’ access to healthcare varies significantly from state to state.
Key Takeaways
- In most states, employers can require a doctor’s note for any absence — there is no federal law restricting this.
- California limits doctor’s note requirements — employers cannot require a note for absences of 3 days or fewer if the employee used sick leave.
- Other paid sick leave states — including Oregon, Washington, and Massachusetts — have similar limits.
- FMLA absences may require certification, but the rules are different from standard sick leave.
- Employers must apply doctor’s note requirements consistently — singling out one employee may be discriminatory.
States That Restrict Doctor’s Note Requirements
Several states with paid sick leave laws limit an employer’s ability to demand documentation for short absences:
California: Under the Healthy Workplaces, Healthy Families Act, an employer cannot require medical documentation for paid sick leave of 3 consecutive days or fewer. The employer can require documentation for absences longer than 3 days, or if the employee takes sick leave on more than 4 occasions in a 12-month period.
Oregon: Employers cannot require documentation for absences of less than 3 consecutive days when using paid sick leave.
Washington: Employers cannot require verification for absences of fewer than 3 consecutive scheduled workdays, unless the employee has a pattern of absences.
Massachusetts: Earned sick time users cannot be required to provide documentation unless the absence exceeds 24 consecutive hours.
New York: Under New York City’s paid sick leave law, an employer can only require a doctor’s note if the employee is out for more than 3 consecutive days.
Vermont: Employers cannot require a doctor’s note for absences of fewer than 3 consecutive days when using earned sick time.
Arizona, Colorado, Connecticut, Maine, Maryland, Michigan, Nevada, New Jersey, New Mexico, and Rhode Island — all have similar protections ranging from no documentation for 3 consecutive days to only requiring it for extended absences.
Does the Employer Have to Pay for the Note?
In most states, the employee bears the cost of obtaining a doctor’s note. However:
- If the employer requires a note and the employee cannot afford the appointment, the employer may need to accept alternative documentation (e.g., pharmacy receipt, self-certification)
- In California, the employer cannot require a note for absences of 3 or fewer days — so the cost is irrelevant
- Some states’ paid sick leave laws prohibit requiring a note from the employee’s own doctor if the employee was not seen — this effectively limits online certificate validity
FMLA Documentation Rules
FMLA leave has its own documentation rules. If your absence qualifies for FMLA:
- Your employer can require medical certification from your healthcare provider
- You have 15 calendar days to provide the certification
- Your employer cannot require a doctor’s note for every single absence if you are on intermittent FMLA leave — they can require recertification at reasonable intervals
- An employer who requires a note for every FMLA absence may be interfering with your FMLA rights
Can the Employer Require a Specific Doctor?
No. Your employer generally cannot require you to see a specific doctor. They can:
- Ask for documentation from your treating healthcare provider
- Request a second opinion (at their expense) in certain circumstances
- Require certification from an occupational health provider if the company policy is uniformly applied
They cannot dictate which clinic or practitioner you see for treatment.
FAQ
Can my employer require a doctor’s note for one sick day?
In most states, yes — but not in California, Oregon, Washington, Massachusetts, or other states with paid sick leave laws that specifically prohibit this.
Can I use an online doctor visit for the note?
In most cases, yes. Telehealth notes from a licensed practitioner are generally accepted as valid medical documentation. Some employers may have policies against online certificates, but these may be unreasonable in states with paid sick leave protections.
What if I cannot afford to see a doctor?
Some states address this by limiting when employers can require notes. In other states, you can offer alternative evidence — such as a pharmacy receipt, a self-certification form, or a note from a community health centre. Your employer is not required to accept alternatives unless state law says so.
Can my employer fire me for refusing to provide a doctor’s note?
If the employer’s policy requires a note and you cannot provide one, you can be disciplined or terminated — unless a state law prohibits the requirement. In California, firing someone for not providing a note for a 1-day absence would be unlawful.
Do I need a doctor’s note for a mental health day?
In states that restrict doctor’s note requirements, the same protections apply regardless of whether the illness is physical or mental. In other states, yes — the same documentation rules apply to mental health absences if your employer requires notes for sick leave generally.
