Even better, here's a source with analyst comments:
Highly Paid Union Workers Give UPS a Surprise Win in Delivery Wars
Here's a gem:
"Yet, while Smith has been able to hold union organizers at bay by relying on contractors,
FedEx Ground’s savings on labor lately hasn’t filtered down to the bottom line. That’s because its 5,600 contractors are mom and pop outfits, many with fewer than 10 employees. They face the same elevated costs inherent to small businesses. They pay full price for vehicles, tires, oil, parts, maintenance, and other items that UPS buys at scale. Each contractor has the same back-office work and often farms it out to third parties, adding to expenses."
and there are many more in the article.
Or I suppose this is one of those bigwig decisions that us common folk are too stupid to understand. Spending dollars to save quarters and all.
