An individualist
The majority of people live in groups or feel related to a group. The group is often strong or close.Then it is almost impossible to avoid, berate and criticize other people from (the thought of) a group. It is rather concern, arrogance and rejection than jealousy, I think.
An individualist (or your own secretary if you like) will not easily start gossiping in my opinion, because he /she is going completely his own way. Standards and values ??will often be clearly different..........
