The four-day workweek is intriguing. I worked for the American Red Cross for a year shortly after college. My boss there was excellent and flexible with my work schedule. I was able to leave early to run track with a coach, and then come back in and finish up any work I still had. It made me much more productive and they got way more work from me than if I had to be there all day, every day. More companies should trust their employees to get the work done.
