I was recently on FMLA when my daughter was hit by a car. There were options on my forms that the doctor could check if my absence needed to be intermittant, which I think is what you are asking. My daughters doctor could check continuous, intermitant, and shortened days. Mine was actually planned on 4 weeks off then 8 weeks working then another 4 weeks off, this was how the doctor wrote it. My daughter had complications and I was off continuously for the entire 12 weeks allowable.

I dont know if that is standard or at the employers option pending on the number of employees.

My employer also has an income protection program. If you are out for more than 10 days unpaid, you can request in writing income protection. Its only $60 per day, but at least it is something.

Good Luck and I hope you are feeling better soon!
