I work at home, so I don't have sick leave. I've worked when I've been sick, and I've also called the office manager to tell her I couldn't work. Granted, if I'm that sick I can always type a couple of jobs, then go lie down, and repeat as needed. I had pneumonia in October of 2004, and after two days I got a call that my account was complaining that their work hadn't been done, and no one would cover for me. So, I got up and did the work. It only took me two hours to catch up.
