What Happened When I Moved My Company to a 5-Hour Workday

The stress of having to do never-ending hours too.
Also the stress of wasting a full long day if I am not in condition, and having little chance to recover for the next one because their is little available time to do so. I would know that I have a much greater chance to recover, that I have wasted only a short day of work, and that I can easily make up for it on the next day because there is a lot of available time to make extra hours and yet not arrive at home at late night.
Then there are more opportunities to practice a bit of sport or any outdoor lighter activity every day or every other day (you don't have to put everything on the only available day(s) of the week and hope that you are in a shape, that you have time, and that the weather is OK, and then cancel...), and that's often good for the sleep, the morale and such.
I was living (and working) much better when I had a 8-4 job (7:55--16:05 home departure--arrival) then when I had a 9:30/10-6/7 job (8:45/9:00--19:30/20:00 home departure--arrival). I could have a life after work, especially an outdoor life, and that more than compensated the often tough wake-up (I mean 'tough' for me, I know it is nowhere close to 'tough' in absolute value :-) ). Pair this with an even earlier ending, and I should be OK.
But yeah, I could take the 1PM-6PM shift too :-)
