In my experience, most employers think this way, but they don't like to acknowledge it. I've had bosses that talk a lot about "win-win scenarios" and how we're all working together to this common goal, all the while creating a very worker-hostile environment where people are pushed to work much more than they feel comfortable with, with regular emails praising the workaholic who works so much he never gets to see his kids. The unspoken message is, this is what we expect of everyone.

These same people get profoundly uncomfortable if you respond to their platitudes with reality. They prefer to keep up this illusion of cooperation, because it makes them feel better.
