This is not a top-down problem, but a bottom-up problem. People want to feel meaningful, so they make up stories of why their job is important, why this or that task needs to get done right now, etc. The only things that are really urgent is when you are a focus point of a political game between two managers. Then you really need to struggle, work overtime, etc. Otherwise usually nobody cares about your existence and you can do whatever you want, as long as you do it in the office building.
