We work 20-hour weeks (remotely) at Apsis and it goes fine for us. We're a small consulting company with very little overhead, but I imagine it could work in other contexts as well. It certainly encourages you to eliminate unnecessary meetings!

I'm earning about 2/3 of the salary from my previous job, where I worked 60-80 hours a week. In practice this has meant a more-than-doubling of my free time outside work with only a small change in living standards, so I'm very happy with the tradeoff.

The company gets a pretty good deal too -- our work hours tend to be quite productive -- but I don't know if there's a purely economic argument on the company's side. Part of it may require looking at the company as a vehicle for employee benefit rather than an opposing force trying to extract maximum value.
