Makes sense. I would say if productivity is below 30% of RTO then it's RTO. I can't imagine that though. Most people are productive 3-4h at most in office jobs, it shouldn't that difficult to measure output/productivity. Just meetings normally takes at least 1-2h on average out of most people's work days.
Well if you're remote you're in competition with the rest of the world right as they're all remote too and will do they same job cheaper so probably a decent one.
