back in the mid-2000's we had a very hot summer and the company I worked for allowed us to switch to 4x10s for the summer. Gas prices were very high at the time too so that was the main benefit from the company point of view. But we had to take either monday or friday off and we had to work together with our teams to make sure we weren't all off on the same day. It was great! 3 day weekend every week, the ability to do chores and errands that are much easier to do on a weekday than a weekend, and cutting out a 1/5 of the commute made a big difference in both sanity and money. But the best part about the whole thing was that because there were some people out on mondays and fridays all meetings were scheduled on tuesday, wednesday, thursday - and you knew that if you had fridays off then your monday was free and clear to get actual work done. It made a huge difference to productivity and morale. I have tried to convince every company ive worked for since to do it and none have, but I will keep trying.
