I work with two other people, one sits next to me and the the other, who is also the manager, sits behind us facing in the opposite direction. The person who sits next to me constantly dozes off, we are talking up to 40 odd times a day, it even happens when they are stood up. I think that they may suffer from sleep apnoea, which I believe is associated with health problems but I suppose I just find it strange and worrying to be sat next to someone at work who is snoring and to be the only one who is aware of it.
Should I mention it to the manager next time we have a private talk or will I seem like I am trying to get them into trouble?
