Pretty much sounds like our barn too. I'm pretty sure it's like that everywhere. A lot of that has to do with too much stock put into the daily projections. If the projections are way off, then the panic ball gets rolling...Not enough stock put into letting the dispatcher use his/her logical reasoning (as you displayed in your original post), but then again...Con-Way hires people who sometimes are unable to reason logically!!
Besides that, Con-Way doesn't want people thinking...someone may figure out how to do it better.
If there's a formula/policy (PRIDE) in place that mandates plans, solutions, results, etc., then consistency across the board is assured. Regardless of how good the outcome may or may not be...that way the ball is out of our hands and they remain in control of results. God forbid, someone show them up...
