I've only met one person who wasen't for a four day 10 hr/day work week.
He was a Electrician acquaintance of my father.
He was beyond a odd duck. His idea of a fun weekend was painting his house. I'm not kidding.
I used to talk to my father a lot over a four day work week. His union almost got it, but they backed out at the last moment. I still think it was a payola thing from the contractors!
It just makes so much sence in certain fields.
Most of my work life has been construction in San Francisco. Just getting to, and back, from the job site is a hassle.
A four day work week would be grand.
Even though the work is back breaking, working ten, or eight hours did not affect productivity, or at least with me.
I would still be an union electrician making twice what I do now if they offered a four day work week.
(This mainly goes for union construction, and office jobs. Non-union jobs work their employees to hard. I don't know how most of those guys even last 8 hours. If you happen to read this, and are in construction try to get into a union. Just trust me.)
