Usually the human-resources department within your company would handle pungent-personnel problems. But if someone in HR isn’t available, you’ll have to tell him in a direct but delicate manner.

First, find a private place to meet where others can’t get a whiff of the conversation. Then broach the topic with, “There’s something I need to share with you, and I don’t want to embarrass you, but it’s been brought to my attention that there is an odor around you that people find unpleasant.” Remind him that his position requires constant interaction with potential customers and co-workers; therefore, it’s necessary to resolve the issue.

Avoid discussing the cause, since it’s more important to key in on the solution. If he’s open to suggestions, offer a specific course of action — for example, fresh clothing for the booth, tooth brushing immediately before booth duty, or more frequent bathroom breaks.

Once you’ve proposed these ideas, both of you should agree in writing that he will follow your recommendations and that you will meet again at a specific future date to determine whether the problem has improved.

If the situation doesn’t improve, you may need to consider transferring him to another position that doesn’t involve as much public interaction. With any luck, you’ll both come out smelling like a rose.
