Collusion? Conspiracy? What's with the UPS bashing?

None of the articles in your document support the theory that UPS is supporting card check. Where do you see UPS pushing and supporting the card check bill? And if you think UPS wouldn't rather be non-union...

UPS executives and the Teamsters union are working together to "remove truck drivers, couriers and other [non airline] employees at FedEx's Express unit from the jurisdiction of the federal Railway Labor Act" The RLA was implemented "to limit commerce-crippling strikes at railroad companies" and has been extended to cover the Airlines as well. (Quoted from the Wednesday's Wall Street Journal cited above.)

FedEx and UPS have the same business model to several decimal places. Either FedEx should actually be covered by the National Labor Relations Act or UPS should be covered by the RLA.

In fact, I believe UPS executives would be just as happy if UPS was granted the protection of the RLA as opposed to taking those protections away from FedEx.

Pick-up a package, move it by truck to the airport, or destination if it can be delivered on time without moving by air. At the destination, put the package back into a truck and send it out for delivery.
Which company did I just describe?

If making the playing field level makes it easier for FedEx to be unionized, so be it. UPS has worked with the Teamsters for many years and still makes a profit.

If you want to get on your high-horse about something, look at FedEx Ground's treatment of its "contractor" drivers.
