Behind-the-scenes during classes?

Hi, I've been an app user for several years and have never had the pleasure of riding live in studio. For those who have, I'm so curious about any behind-the-scenes info. Like are the instructors looking at a screen w/the leaderboard and then their class programming and notes with timing? It would be weird if they were staring at their own live class.

Also, they seem to have an earpiece that I guess they can hear their producer in case there's anything urgent?

Finally, I know some of you have worked for fitness companies before and am curious what kinds of things are specified in their work contracts. Obviously the specifics of their job like how many classes per week, professional dev requirements, non-compete, etc. but it's clear they can't endorse a political candidate publicly (human rights general topics are fine, and that's a good thing), have a code of professional conduct (oliver's termination), and maybe have to stay within 10 lbs of their hiring weight or something like that.

Interested in the behind the scenes if anyone has thoughts on this....
