To be honest, though, the average worker doesn't have that kind of leverage, they don't have pockets deep enough to wade through the interview cycle, and many of the other employers they'd go work for are doing exactly the same thing. For them, the alternative to employment at a company deploying these kinds of tactics is very much destitution - especially right now.
I'm with you on one thing: if my employer demanded minute-by-minute accountability for my time, I'd leave, no questions asked and minimum notice given. I have that choice, though; when discussing things like UBI, I always try to remind myself that someone for whom that support would be life-changing is in a very different situation from mine, with a much more constrained set of responses / actions available to them.
