Meetings are one of the major ways in which power is demonstrated and exercised in hierarchical organisations. Trusting people and leaving them alone to get on with stuff is more productive, but work isn’t always about productivity (sadly).
Meeting abstention: Anyone invited to an internal meeting has the power to opt-out. “Send me the summary, please.” If someone abstains, they give up their ability to have a say in the meeting, but most meetings these days don’t actually give people a platform to have a say. And then that person can leave the Zoom room and get back to whatever it is they were doing that was actually productive.
Meeting nullification: If anyone in an internal meeting announces that the meeting is a pointless waste of time, it’s over. The meeting organizer is obligated to send everyone the memo that they probably should have sent in the first place.
