Experimental findings published in the Journal of Applied Psychology revealed that employees who had their cameras on during virtual meetings experienced greater fatigue and, in turn, reduced performance during meetings. This was especially true for women and newer employees, suggesting that a heightened need for self-presentation may be the cause of this fatigue.

This is why I cringe when I hear schools going remote and trying to run their classrooms as if they are in person. No, you can’t expect all of the students to have their cameras on at all times and not run in to issues.
