This sounds very fishy. Not on part of the employee, on part of the company. I worked and have friends work as salaried workers in creative positions in huge corporations and they all share one thing in common... if they are asked to stay overtime they get paid for that overtime.
Often they are not asked to stay overtime, and can leave at the end of the workday, but they would not have as much work on the wall so to say. Most prefer to just simply leave, pulling maybe 1-5 days a month actually staying late to finish work.
With multi billion profits these companies are churning out, its time for devs to start class actioning one company after another. Trust me it wont take long before these parasitic executives fall in line (or fall off like vestigial limbs). Doesn't take much to start a non-profit lawyered up sue cannon organization that watches anonymously and strikes when appropriate.
Don't quit whining on blogs, the more the better, but don't forget direct action as well guys.
