It's one of the "possible, but not really viable" solutions I think. I'm probably not going to coordinate schedules in order to have a chaperone present for all of my meetings, not going to cancel meetings when the chaperone is sick/on PTO, not going to take the chaperone on all of my business trips, and probably not going to discuss confidential business topics (upcoming mergers, divestitures, or budget problems brought on by carrying 1/4 of our headcount as chaperones in the company, etc).

Most of these places have seccams every so many feet from each other. Team rooms could have them w/o audio so people can feel at ease to express themselves while also having a silent witness in the event of any physical aspects of the meeting were to come up --obvs there are some limits as most have a def retention of 30 days.
