How do I tell a co-worker he smell like raw sewage.?
Tell your boss or HR. If you tell your co-worker yourself or leave post it notes or toiletries, you WILL create a hostile work environment. Get some air fresheners in your cubicle or dab your nose with droplets of peppermint oils or lavendar in the time being. It will burn but heck, better than smelling crap all day.
unless you plan on hiring him a maid, you must know that this isn’t just an office smell. His smell may come from the stale air in his home, and sticks itself to him and now his office. I suggest putting nice smelling things in your cubicle/desk area so you have something nice to smell, because there isn’t really anything that will break up the scent. Do not leave an secret note, because that’s childish and would make him feel two bits tall. If you want him to be aware of this odor it is something that you would have to sit down and talk about~like adults. If don’t want to talk to him, then ask a supervisor. I REPEAT: A SECRET LETTER IS STUPID AND CHILDISH. YOU’RE NOT IN MIDDLE SCHOOL YOU ARE BEING PAID FOR SERVICE. EVEN THOUGH HIS ODOR IS NOT PROFESSIONAL IT DOESN’T GIVE YOU A RIGHT TO NOT ACT LIKE A PROFESSIONAL.
