I am on video calls a lot and have even been doing (obviously remote) video recordings. I have "good" Internet, which is to say it is "occasionally" glitchy which is to say less than often but more than rarely. Not often enough to persuade Comcast that something in wrong.
Murphy's Law suggests that that one of the times it glitches will be during something important. (It has done so during a couple semi-important things over the past 18 months.) Absolutely nothing I can do about this although I try to fall back to cell phone--although doesn't really work for video.
My entire point is that in those roles the quality of your connection matters to your work quality and thus the onus to ensure it works.
