On a related note, as a parent I think school perfect attendance awards are perverse. Congratulations, we're rewarding a kid for being a disease vector and being sent to school miserable and snotty, or at best making other kids feel less-than because they received proper treatment and isolation. I would guess that the average perfect attendance kids costs the rest of the school at least half a dozen absences per year.

That gets other people sick and is counter productive too. You end being sicker for longer, it's a loss for you and the company. It's just dumb.

I was a department manager who shared office space with another department. One of the guys from the other department came in bragging that he had been throwing up all morning but was able to come into work. I told him he either needed to sit somewhere else or go home because I’m not risking my health or the health of my colleagues/associates because of his dumbassery. He eventually went home after I gave him a verbal dressing down that his manager backed me up on.

So selfish to come into work sick like that!
