Management really believes that the open space is more collaborative and has a better "buzz" that really does feel, to the manager, like more work is getting done.

Of course, employees hate open space. Constant distractions, and the pervasive feeling of being watched by everyone, all the time.

It's really interesting that management is so out of touch. (I say this as a manager who loved big open offices, until I read on HN - 1000 times over - how consistently employees hate open offices).
