re: How to tell co-worker they smell?

I actually had to do this with a one of our millwrights. Dude didn't take a shower for three days and his roommate at the hotel came to me to complain about it. I finally had to tell him either he was going to shower and he was going to unemployed. Working 12 hours per day in 100F temps in a paper mill, then he would get back to the hotel and go to sleep. It was disgusting, and we made him pay for the damage the hotel charged us for getting grease all over the sheets and mattress.
