No, they aren't. But they aren't as infallible as you seem to think either. FedEx has lost plenty of costly legal battles. The issues surrounding Ground aren't going away because the ISP model is legal (for now). I expect more investigation and litigation, with the ISP model eventually found to be illegal as well.
It's coming, Scammy.
The biggest issue I have is a lot of these are
#1 old lawsuits that went class action!
#2 most of these owner operators i.e. contractors are long gone
#3 as well as the horrible managers that were brought in from the outside are gone as well!
#4 most not all, but most of the lawsuits stem from the opening of home delivery and as stated above; if these are won or lost by either side most of the players are out of the game! Sure maybe a contractor gets paid, sure maybe fedex pays taxes.
Do you realize that as ground keeps growing at double digit numbers year over year they are going to soon be grossing a BILLION a year! I remember when ground first made a Million! Look @ earnings each quarter and yoy!
