A friend from college does software dev for a place that does 4x10-4 and he said the way the fixed issues was by asking for ROI on everything you do. Need to schedule a meeting? Is it worth the cost of people's time? If so make sure you get the right people, habe everything planned out before calling it so you get your work done promptly.
At first everyone was like fuck, more crap you have to do. But eventually they figured out that much of their time was wasted on crap no one needed to do. Some people stuck around for an hour or two after work to hang out and others took back their lives. Productivity actually increased because people were not as burned out.
