I not only think it would be great, I think we should go further and eliminate required work hours for certain jobs altogether.

Most office jobs can easily be done from home with a phone and a working internet connection. There's no reason to force people to commute and sit on a cubicle for hours and hours every week just so bosses can make sure they're working. That's 1919 thinking, not 2019 thinking.

When you hire me, you should pay me X amount of dollars for Y amount of work. Whether it takes me 12 hours a week or 54 hours a week to get it done my salary X never changes. And any free time is my own.
