FedEx is non-union. They spend an insane amount of money marketing themselves as a good employer (all that, "Truck driver to pilot" bullshit).

I've have friends who were freight truck drivers talk about it. A lot of young kids get sucked up into non-union shops and are told about how much better it is; how they shouldn't want a union. Most of the unionised freight companies do pay better though; or if they don't, they make up for it with more benefits and lower road time.
