I don't turn on my camera for meetings. You really don't need to see my face. Anyone who says otherwise is not a serious person. We have been multitasking while on the phone for decades. This is no different.
I think it's OK to have the camera turned off for meetings but if it's a company meeting or a more social catch-up I'd like to see my co-workers. So 99% of the time no problem. But once a week or once a month I'd like to see everyone.
Do you never nod in agreement when someone else is making a good point. Or use hand gestures? Also you can smile at a joke when you have your camera on. Sometimes it’s nice to have a joke with colleagues.
Nice, but not required. I can share a joke fine over a phone call.
