A federal appeals court on Tuesday upheld a lower court ruling that UPS Inc. violated anti-discrimination laws by automatically barring the deaf and hearing-impaired from driving parcel delivery trucks... "UPS strongly disagrees with the court's ruling and we are evaluating our options, including an appeal," company spokesman Norman Black said. "We believe this case is about safety. It has nothing to do with disability or discrimination."... The U.S. Postal Service and FedEx Corp. allow some deaf drivers to operate delivery vehicles under 10,000 pounds.
