It's not Stockholm Syndrome to trace the history of American corporate governance in my lifetime to find that discharging obligations in bankruptcy has become an openly sought-after outcome for the executive class. It also isn't Stockholm Syndrome to see that established case history has put laborers with decades of pension contributions firmly at the bottom of the unsecured creditor list in bankruptcy cases - especially airline bankruptcies. The consequences of this cultural devolution came as a devastating shock to my parents when I was a young man, but I was at least afforded a chance to learn from their experience and plan my adult life accordingly.
...or that might just be my post hoc rationalization when I rightfully get called out for being an openly distrustful, mercenary little s**t.
More to the point, anybody who values their pension plan in this day and age needs to go to great lengths to protect it, precisely because it is one of the last vestiges of a functioning social contract, and it's catnip for predatory carpetbagger MBAs. Personally, I do not think the FedEx TA accomplishes that. It firmly settles the question of whether the company has an obligation to protect the pension plan for ALL FedEx pilots, and all but ensures the future mismanagement of same to the increasing apathy of future employees.
That's just one outsider's opinion on the internet, of course.
