Aww! All this while, I didn't know RTO came from a place of genuine worry and care about your workers. There I was thinking, that RTO was more about control and domination. Forgive me master, for I knew not.
If you're remote and there's an "upgrade" remote job, there's very little friction to switch beyond the usual onboarding. You don't have to find a local job for your spouse, sell your house, switch your kids' schools, etc. You just mail your old laptop in and wait for a new one to arrive. Maybe you have to get up early or work later to match the local time zone if you have many in-office coworkers.
And, if you work at a big company that pays well, it can also let you get off the hamster wheel early and "leave your job" for retirement by moving to a medium- or low cost of living area while continuing to get paid an outsized amount for the area.
