Under my union contract, I get sick and vacation days. First day sick is taken out of vacation -- kind of covers those mental health days without using up your sick leave. Of course, in my case after 3+ months off last year, I don't have much sick or vacation time to use.

My workplace is the direct opposite of Trek's -- you can't swing the proverbial dead cat without hitting some sort of H1N1/Flu prevention flyer, poster, email, dancing bear.....
