Would you rather
Work 8-12 (or 9-1 etc.) every Friday
Or
Work 8-4 one Friday and have the next Friday off
And why!
I'm in the fortunate position of having some choice over my hours. The regularity of the first one appeals, but maybe it would feel more like a day off in the second one. I'm actually planning on doing some personal studying so it's not going to really be like a day off for the most part.
