Wow ... this story reminds me of Marshall Brain's Manna story.

I don't understand how much money a company would lose if they changed the hours to 3 or 4 hours per person. Fine, they'd double or triple their workforce and have to deal with more HR/paperwork. But the costs don't increase. This makes me wonder if the reason is not cost but control. If company X is the only thing in your life, you will likely be a more "compliant" worker. This kind of stuff scares the heck out of me :(
