Presenteeism is when employees come to work when they're sick, as opposed to absenteeism, which is when employees don't come to work when they're not sick.  The New York Times (via Lifehacker) says you should stay home when you're sick, but I don't.  Unless I'm physically unable to perform the rigorous task of sitting at a computer all day and occasionally walking down the hall to get food or talk with co-workers, I go to work.  And really, the only illness that would make me physically unable to do these things is when I'm puking.  If I have a runny nose, sinus congestion, sore throat, cough, phlegm, or any other standard illness, it's almost never bad enough to make me stay home from work.  I guess I could stay home, what with the ridiculous amount of sick time I accumulate, but if I did, I'd pretty much be doing exactly the same thing as if I went to work:  Computery things.  Plus, by spreading my germs to otherwise healthy people, I'm helping their immune systems develop the necessary antibodies to fight off whatever virus I have.  So really, I'm doing a good thing by going to work sick. #health
