One summer I had my wisdom teeth removed and went back to work after one day. There has only been one time where I was too sick to work. It was a terrible stomach virus that lasted a week, but I was still able to show up to one of my jobs (I had two at the time) on the days I wasn't puking my guts out. If I'm breathing I'll go, because you eventually get better and being behind and loss of pay lasts longer.
