Wow I’m surprised at the heavy downvoted here.

I don’t think mandating cameras on and insisting on 100% is the right move, but I definitely think you want to aim for a team culture where camera-on is a default and most people have them on 80-90% of the time.

Otherwise, yea participation and engagement seems to take a major hit.

I think some people are misinterpreting 100% as "even when you aren't on a call/Zoom/huddle" which is batshit.

Some people are just unhappy they're being called out for taking meetings while they take a dump.

The latter is precisely why attempting for 100% cameras on during meetings is a good idea. If you're uncomfortable being on camera in a meeting doing it, its a good sign you shouldn't be doing it.
