I really dislike the idea that people should be required to have their cameras on for all meetings. I think for people who rarely see one another in person, it can be good to try to encourage people to be on video occasionally, but when and how often should really be left up to the individual. As a manager, I make it a point to try to turn my own video on most of the time, but I'd never ask someone to turn their came…
A decent, humane manager. At my company, all the ICs I respect have camera off meetings. Only managers, obnoxious ladder climbers, and outside consultants are constantly pushing face time.
For individuals choosing camera on vs. off when participating in meetings, whatever the choice, I bargain more than would admit are making some form of status calculation.
Personally I bias towards on often as it feels more... friendly?
