Suggestion for a new GFT policy to implement

I have a suggestion for a new policy at GFT, when comes into work sick they must wear a face mask to protect others from being infected with the sickness. This is very common here in Japan. At first when I was walking the streets I was a little taken a back by this. It seem so extreme and almost plague like. I wanted to make sure that I avoided these people because it seem so serious to have their whole faces covered. Then one morning one of the sales guys came into the office with a mask on, I immediately wondered if I should have gotten all my shots before I came to Japan. I have gotten comfortable enough to ask Emily why they are wearing this and she informed me they have a cold...Now that I know that these people just have the common cold, I love this idea and I am less afraid. I want to thank them for being considerate not to pass their germs on to me. But I don't' know that right words in Japanese to say this. Think of how many times we have passed around sickness just within the CS department and got behind on work because people have been out sick. Some people can't afford to take off time, so they come into work and sneeze all over the paperwork infecting everyone that touches it. UGh... had they worn a mask, this could have been avoided. Something to think about, Gary, if you are reading this. You could put the GFT logo on it... Give them an occurrence for not wearing it or better, an occurrence for every person they infect. Hahaha. I love it.
