I'm not trying to be a smart ass, but if you make make $x amount for a 40 hour work week at $y/hr and then reduce your work day by an hour means you would make $z = ($y*35hrs) = $x - $y*5. But since I'm not thinking about it correctly, I'm assuming that these people are not getting paid more to make up for the difference. How should I be thinking about this? All of my assumptions are that everything else remains constant...Prices, food, bills, etc etc
Then again, after reading your profile on that section, it doesn't make reference to money. I'm neglecting the other gains that a shorter work day would bring such as, time with family, personal, etc etc. I'm just focusing on the financial aspect of things.
Now I will admit, I used to work for the state and thus was forced to have Fridays off without pay. And that was rather nice. Instead of working a 40 hr work week, it became a 32 hr work week. This allowed a lot more free time for my personal work, hobbies, interest, and life and I found it rather enjoyable. However, I was not compensated financially for this. But I made the necessary changes to alleviate the financial tension.
