I work in a small office where we each have our own private offices, with close proximity to one another’s door. My co-worker has a tendency to belch loudly constantly throughout the day. And on top of it talks really loud when on the phone (most of the calls are personnel). I know that he can control the belching in meetings, but when in his office lets them rip. My other office mates have noticed as well. It gets so bad that we sometimes have to put on noise canceling ear plugs.

Any suggestions for how to deal with this? I’ve had just about enough of this gross and rude behavior.

Thanks
