Re: @ The Onymous Coward
@DougS - I agree; my point was more that the long sabbatical is much more prevalent than it was even ten years ago. We're /on the way/ to working fewer hours, but I'm not sure whether a legal, cultural or economic impulse will usher in the 4-day week.
I would suggest that most office-based staff already do a 4-day week by dint of long lunch breaks, copious web browsing and the odd day "working" from home, but it would be nice not to have to pretend.
