> Manufacturing was, logistically speaking, easier to organize. There were lots of workers at each factory, and most knew one another. Service work is more dispersed and done in smaller crews.

Fostering a sense of trust and shared purpose under these conditions is difficult. Plus you can't just fire everyone and shut down the factory when they start talking union.
