I strongly believe that managers get the staff attitudes they deserve. In a small way I've seen it close at hand, when a department had a manager who built his staff into a silo mentality, with the result that things took twice as long as necessary, and most dealings with them were a hassle. After a couple of years a new manager took over, and within weeks attitudes changed. As a result the department were miles easier to deal with, and the work they were delivering also increased in quality. All because the message from above changed.
A lot of similarities with the Gordon Bethune turnround of Continental - wonder if any BA managers have read his book? I'm sure it wasn't all milk and honey at CO, but it was certainly better than it used to be.
