I was wondering what you would also say on what I asked for EBH. When it comes to etiquette during lunch meetings or seminars or board and office meetings, what are types of behavior that cross the line from simply being individual quirks to being disruptive to the point that they become too hard to work with?
The three things most disruptive are bringing up subjects people should avoid at a workplace: politics, sex, and religion.
That said, a person with an obnoxious personality who is loud and tries to dominate all conversation. On this, I know it well as I worked for such a man, my direct supervisor.
