I have a friend that worked in NYC in part of the DOE (not a teacher, but something adjacent). Its a union position, so during COVID when everyone was getting remote, her profession got remote too.

53 minutes per week.

53 minutes. Not even a full hour. It was specific enough that you knew some bureaucrat went out of their way to hyper optimize this, creating a maximum slap-in-your-face effect.

This 30 minutes thing feels the same way.
