Isn’t this the classic productivity blunder? Did these people actually “behave better” because of the change that was being made, or simply because they knew they were part of an experiment? Apparently someone was monitoring there behavior, if they were aware of this, or even just suspected it, then of course their behavior “improves”.

More generally, something had changed, and change induces change. I’d be curious if these behavioral and attitude changes continued for the long term, or if, for instance, Thursday simply became the new Friday.

I’m all for spending less time at work, but this strikes me as an experiment with a lot of potential holes.
