Raise it with your manager, if it's peer's discussion then someone should moderate. When my team has meetings, I moderate. I make sure those remote get to speak first, and then I make sure no one is speaking for too long and call other's by name to add their ideas. If someone interrupts, I cut them off and tell the person that was speaking to continue.
Is there no sense of personal accountability at your company? Why can't your workers be trusted to take care of simple, everyday social problems like this?
I don't like interrupters any more than the next person, but i consider myself an adult and want to work with adults -- I can't imagine needing a babysitter like this.
I would say it is all too common in most social situations. It's normal that people get overexcited. People should behave, but often do not. What one is supposed to do when it happens? Find a new job?
Do you also have opinion, that generally working with adults one does not need a manager or a superior? Managers manage people, they should manage meetings.
This usually doesn't happen, but when it does happen it's my responsibility to fix it since I'm a manager. This can happen when talking to someone from a different department, and outside vendor, etc. Like folks mentioned, this happens when people sometimes get very excited and don't really mean to be rude.
