Are they talking about a four day work week where the hours are reduced or are they talking about moving those hours to a different area? For example, in the summer we move to a four day work week, but instead of working 8 hours per day, you are supposed to be working 10 hours per day, then we close the district down on Friday. They call it "four tens"
As I understand it, it is a four day week with same hours, but the details of implementation that I have found were a bit sketchy.
That makes sense. It leads to some really long days. I usually get a bit burnt out when we do it because I am so tired through the week. The three day weekends are nice though and it frees up some of my PTO days for other uses.
I would be happy with 10h days I think. I used to do them every second week when in Australia for a job, and I quite liked the extra days off.
I think my problem was, I still liked to get home at the same time each day, so I would go in two hours earlier. Of course back then I wasn't getting up early to exercise either, so it's all kind of a wash now. All I remember was my wife wasn't very pleased with my attitude and demeanor during those times.
