FedEx, UPS Brace For Battle On Labor Issue, Despite Delay - Smart Money Debate has been delayed over a proposed labor provision that has pitted FedEx Corp. (FDX) against United Parcel Service Inc. (UPS), but the two package-delivery heavyweights remain girded for an inevitable fight. The U.S. Congress last month put off consideration of a bill reauthorizing the Federal Aviation Administration by opting to continue funding the agency through Dec. 31 under its current authorization. The existing FAA bill had been set to expire Sept. 30. "We're in a marathon," FedEx spokesman Maury Lane said. "This isn't a sprint."
