Summary

Your employer may ask for a doctor’s note when you take leave to care for a son, daughter, spouse, or parent, or when you take leave for your own serious health problem. You must give that note on time. The note must say when the health problem started, how long it will likely last, the medical facts the provider knows, and either that you are needed to care for the family member (with an estimate of time needed) or that you cannot do your job. If the leave is for intermittent or reduced-schedule treatment, the note must list the treatment dates and how long each will last. If your employer doubts the note, it can pay for a second medical opinion from a provider not regularly on its staff. If the two opinions disagree, your employer can pay for a third provider chosen by both you and the employer; that third opinion is final. Your employer can also pay for follow-up certifications when reasonable. For some other leave types, the Office of Personnel Management can set rules about the timing and form of the required certification.
