Well, you took it as a challenge anyway. While there are examples of the younger generation failing to keep the company in good health (one being A-P-A Transport, North Bergen NJ), FedEx is a little big for this problem.
The main reason companies have failed under deregulation is a failure to adapt to said. The Teamsters have failed as an organization, because they have been in trucking longer than any of these companies. They should have foreseen the effects of deregulation, and worked with their employers to change the operations to meet the shippers and receivers needs. The fact that the nonunion company's have grown so much in the last 37 years, while the union carriers have either gone bankrupt or shrunk to a pittance of their once mighty footprint, is the fault of the union.
