If I got the projects assigned to me done in 10 hours, I would just be assigned more projects instead of being allowed to take the rest of the week off. That seems to be the culture of my company: productivity is punished with more work, rather than rewarded with extra time off. My boss jokes about it all the time by saying "no good deed goes unpunished around here" but he doesn't realize that it's not a joke. It's reality. :(
