A data point from my world, which is in Canberra (our capital) government world where security says that if you’re doing admin work - basically you’re using your elevated privilege account - you must be in the office.

8 of the 9 people in our database support team left because they just didn’t want to do this. They easily found other jobs without this requirement. We basically can’t hire anyone else because when they learn that they must come to the office, they lose interest.

And Canberra is fairly small and we don’t have a traffic problem worth mentioning. Getting to work is easy. People just don’t want to now that they know that they can work from home.
