I don't agree with working like this, but I'd expect that you're generally going to get marginal gains from each extra hour worked (up to a point of exhaustion or burnout), especially in the short term, so it might make sense to have people work in this way _occasionally_. I know I've been on "work all the hours available" projects in the past, and I definitely got a lot more done than I would have just working a 40hr week, even if I did feel like cr*p at the end of it.
