i didn't quit. it is a job that i'm required to drive around and walk around office buildings. you can't do so with crutches.
i didn't sprain my ankle either. i sprained my foot. the doctor told me that this is a bad case of a sprained foot. it could take weeks to heal. i'm not allowed to put any pressure on it.
that's why you have a doctor's note & your job excuses you until you heal.
