During a meeting, a co-worker raised his voice at another co-worker. The other co-worker repeatedly asked him to lower his voice. The yeller’s reason for yelling was the other person kept interrupting him before he could get his point across, and he had to yell to get his point across. The boss understood the yeller’s reason. My opinion is if you feel interrupted you should ask the person to give you time to get your point across. Yelling at someone is intimidating. The feeling of intimidation could cause the other person to keep defending himself with interruptions.
