I see. I don't have experience with the public sector myself but what I meant is this: If I have only a 4 hour workday, people(bosses) think twice about wasting my time with useless meetings. Also it gives me energy to start into a day with only 4 or 5 hours ahead instead of 8h+. Of course having a shorter workday doesn't make it 100% productive. But my personal experience is that it is MORE productive. Sadly most of my days are 8h+. I also want to add that a tired, worn out developer might even cost productivity by introducing flawed code into the codebase. Did you ever do a serious code review while being tired? I don't see how that works. Then others have to deal with all this stuff afterwards.
