Bonus and possible stock awards
Generally overworked. Leaders push too far and cut costs at the same time. Also, middle mgmt needs a facelift, you can't just rely on those managers to be good, you have to train them, no one is a natural-born middle manager...
Hard (fun!) work, great people, and happy customers.
