Q: Can I require a doctor’s note when employees are absent due to illness?

Q: I hired a new receptionist who started this past Monday. A week before her start date, I sent her all the onboarding forms including a W-4 and Form I-9. On her first day to work yesterday, she presented her driver’s license for List B of the Form I-9 but asked me if she could show me a copy of her social security card instead of the actual card since she lost it during a recent move. After a quick Google search, I let her know I’d need an actual document from List C of the Form I-9, since she also let me know that she does not own a passport.

Today was Day 2 for her, and she still tells me she does not have her social security card. I let her know that by law I am supposed to complete her I-9 within the first 3 days and asked her to bring an acceptable document from List C for tomorrow.

My question is–what do I do if she shows up to work tomorrow without an acceptable document from list C again tomorrow?
