Updated from 11:27 a.m. EDTAs organized labor has gained ascendance with the election of a Democratic president and a Democratic Congress, FedEx ( FDX) has staked out a position as a leader of the opposition. Democratic gains have boosted support for two measures that are important to labor organizing -- and anathema to FedEx. One is the Employee Free Choice Act, or "card-check" bill. It would enable a union to be recognized if a majority of employees sign cards requesting one, rather than allowing companies to call for secret-ballot elections. It would also enable either side to request binding arbitration if a contract agreement cannot be reached within 120 days of an election. The momentum in favor of card check slowed this week, when Sen. Arlen Specter (R., Pa.), who had been considered a key swing vote, reversed a previous indication of support and said he would oppose the bill. Now the act's future is unclear. Also in play is FedEx's classification under labor law. A change could potentially make it easier for unions to organize and would require FedEx to be treated in the same way as its principal competitor, UPS ( UPS). FedEx stridently opposes the change, saying congressional approval would force it to abandon plans to order 30 new aircraft from Boeing ( BA), potentially dealing a blow to the fragile economy. At a rally in Los Angeles on Thursday, Teamster leaders, social activists and U.S. Rep. Linda Sanchez (D., Calif.), excoriated FedEx and released a report entitled: "Keeping FedEx Jobs in the Middle Class in Los Angeles." Teamsters General President Jim Hoffa says the report "tells us what we know (about) the vicious anti-labor atmosphere that prevails at FedEx" and "shines a light on the cockroaches at FedEx."
