You're ignorant.
FedEx offers the ISP a deal with the ISP taking on all of the expense and all of the risk and the ISP takes it. FedEx doesn't know or care what the expenses are. Why should it? Those expenses aren't cutting into its bottom line.
LOL. Fred kept the contractor model because THAT WAS WHAT WAS SO APPEALING ABOUT THE DEAL.
You've got all sorts of opinionated nonsense to explain why you think it'll work. I'm dealing with the realities of why it won't -- the same realities that FedEx and anyone with even the most basic analytical and actuarial skills can see from miles away.
They aren't going to give up great money that they get with very little effort for the sake of good money that would require substantial investments of time, money, and risk.
Not trying to invalidate your points, but the overarching criterion in my mind is, is the model sustainable?
You don't see constant challenges to Express' employer/employee standard playing out in court.
Betting on a horse that you consistently have to modify is risky. Soon, you run out of options to adapt.
If you're only interested in the next race, then gamble away.
Since FedEx is placing its pension benefits in the hands of Metropolitan Life, my horse just left the track.
