Meetings running over is avoidable. People just need to stop enabling bad behavior.

I work with a PM who is notorious for meetings running long. People just start hanging up while she’s talking if they have another meeting to go to. When she start hearing a bunch of beeps of people leaving, she starts to get the message that she needs to continue on the next meeting and stop. People are tired of it and don’t entertain it anymore, as much as she keeps trying to talk.
