Having to tell someone that their breath or body odor is offensive may be one of the most awkward situations you'll ever face in the workplace. Yet sometimes it's essential to act, not only for the comfort of you and other coworkers, but for the company and the person's future as well. Such problems are almost certain to undermine the image of the company if the offender comes into contact with clients. Hygiene problems will erode their standing in the company and will block any further progress in the organization. Begin with the assumption that they aren't conscious of the problem. Start off by subtly suggesting the same tools you use to avoid similar problems. If they take the hint, let the matter drop. If your subtext isn't understood, you'll have to press further while still being somewhat diplomatic.
