I like this better in theory, but my experience is that, given my current hours, work tends to very frequently spill over until later in the evening. If my day was supposed to end at 3 or even noon I don't think it would make a practical impact on how late I worked. Work spilling over into extra days does happen during crunch times, but is much rarer. Though I likewise fear that 4 day work weeks would simply mean you end up working 8-8 everyday to get the same amount of stuff done.
