if we ever get the four-day work week how would you structure it?

Quit entirely, go on the dole.

No, seriously I almost always have a 3 or 4 day week as it is, but it can be variable depending on semester.. everything from having Friday through Monday off (four day weekend),to having two weekends (Sat-Sun and Tues-Wed).

There are also jobs where you do six months on and six months off.  I've met truckers who do this, and oil drilling rig workers.  That'd definitely be my preference in such an industry.  Work hard for six months, get paid for twelve.

Yes you meet quite a lot of oil and gas or mining types in Thailand on their six months off (though probably more do three on and three off).  They work mainly in Australia, Papua New Guinea, and in various offshore-platforms and a few from the Middle East.

yeah, I always meet them if off-the-wall places.  In Guatemala I once met a guy from Massachusetts who does six months on and six off.  He was a trucker.  In Peru, I met a guy from Oregon who does three on and three off.  He was on an oil rig.  It seems like a sweet deal, to be honest. 

You don't really see them in 'off the wall' places, you see them in precisely the places where you would expect to see horny guys with lots of cash - sex tourism places.
