I'm sure none of this applies to any of us here, but I've heard rumors that some people need deadlines to complete tasks. As in you set a deadline, and it doesn't really matter when, and check up with the employee on a regular basis. The interim feedback is always that things are coming along, but there is an awful lot of office chit-chat, browsing Facebook when I walk by, etc.. And then one week before the deadline all of a sudden there is griping and moaning about crunch time, but now there is sudden focus, and things get done. I'm a new manager, so I wish I had a better way to work with this dynamic. Smaller milestones? How small before it becomes micromanaging? But to the main point, if you are routinely working 70 hours a week that is a toxic work environment and you should leave.
