It's really sad when you're just starting to explore a service that others have spent more then two years bringing to maturity. It's all too easy to fall behind when you're distracted by your unionized workforce's insane demands and work rules. High-performing companies always have an external focus. Unions demand an inward-looking focus that ignores the competitive landscape. I certainly hope YRC Worldwide isn't entrusting the application's data entry or interface design to union labor.
Full disclosure: No positions in YRCW, UPS, FDX, or CNW at this time.
