In any case wfh is not a win/win. The employee has to pay for everything such as heating, Internet, they lose a room or more for their enployer, they lose the daily human contact. And that's just starters. It's an abuse of employees unless mutually agreed. And from recent experience a major downer for the public trying to get a company to do something, even answer a phone in good time.
Meanwhile, maybe many decided they didn't need to be judged in the rat-race and opted to retire early ?
