I think that's partly the issue. Everyone this guy is exposing this stuff to, has the potential to then expose their children or grandchildren, or others who could really be adversely affected (not to mention lost production time when other employees start getting sick).
Last week we had a B-day get together for the Father-in-Law. An Aunt that works at the hospital was told NOT to go by Doctors there because there was a risk that she could potentially infect a couple people who would be there that had heart issues.
Edit: Also, what person would even want to be down like you were? (Not picking on you, just using the example you put forth) Down for that many days, losing that much weight, isn't good for healthy peeps either. I'm sure you felt horrible (as anyone else whose been there has), and why risk putting someone else in that position? I understand money issues, but one shouldn't put themselves above others when it comes to potentially infecting them with something that causes them misery.
