Although I don't like to reveal UC, you might have to clue your coworkers in, in this situation.
A while back someone talked about a spray air cleaner that is used for sick rooms, that doesn't have any smell but really does a good job at killing odors. You can get it at medical supply stores and they sell small bottles that you can carry in your pocket. So you can use it discreetly. I wish I could remember what is was called, but you might find it on a medical supply store website, or at a medical supply store. It was a biological odor eraser, I think they called it.
I never tried this until my hubby suggested it: spray into the toilet bowl, even while you are still on it! That works pretty good.
