Also, it't not even a bad deal for employers. Binding time spent to money taken home like everyone is a blue collar worker where output is approximately linear (or, an a moving assembly line, actually ideally linear) doesn't work for knowledge based jobs, especially if they involve creativity. Productivity goes down the longer you work.

I switched to a 32 hour week and I don't feel like my productivity is impacted beyond not being able to attend some meetings, most of which were superfluous anyway. If it's really important I will make the time elsewhere, but that has happened once or twice in ~8 months.
