Is it disrespectful to leave a meeting midway?
If you leave a meeting early, it has one less participant – one less source for ideas and exchange. But you have also allowed those who remain to proceed with more focus.
When you leave a meeting early, you indicate that it is no longer relevant to you. But you also convey that you are no longer relevant to it – that it has one less potential source of noise.
While leaving a meeting early, you momentarily disrupt the meeting. But the rest of the meeting can proceed with one less passive member, and into a more meaningful exchange.
Is it disrespectful to leave a meeting midway? Well, that depends upon how you define respect. If your idea of respect is for people to suffer through a meeting for your sake, leaving midway would be most disrespectful. If your meeting is meant to be a meaningful exchange, those who leave because they are no longer relevant have just done everybody else a service.
