As Delta Air Lines works toward its proposed merger with Northwest Airlines, labor unions at the highly unionized Northwest are ramping up efforts to organize employees at the largely nonunion Delta.

The International Association of Machinists and Aerospace Workers, which represents about 12,000 employees at Northwest, has opened an office in Atlanta across the street from Delta's headquarters for its ongoing campaign to organize Delta employees.

A union wanting to represent a segment of Delta's employees must get signed authorization cards from 35 percent of the workers involved to force an election.

And at the Association of Flight Attendants, committees of flight attendants from Delta and Northwest are working on a campaign to try again to organize the attendants at Delta after the merger is complete.

The flight attendants union lost an election to unionize Delta's flight attendants in May. They plan to file for another election after Northwest and Delta combine. Flight attendants from both airlines would vote in a combined election on whether to be unionized. Northwest has about 7,000 flight attendants; Delta has about 14,000.

"If this merger goes through and there is to be another election, this will be one of the largest union elections in the country," Association of Flight Attendants spokeswoman Corey Caldwell said. Northwest flight attendants "have a lot to lose if they lose their contract," she said.

Only one major group at Delta is represented by a union — its 7,000 pilots. About 200 dispatchers also are unionized. Northwest employees are represented by the Air Line Pilots Association, Association of Flight Attendants, International Association of Machinists, Transport Workers Union, Aircraft Technical Support Association, Northwest Airlines Meteorologist Association and Aircraft Mechanics Fraternal Association, among others.

The Machinists want to organize ramp workers, customer service employees, reservations employees, maintenance workers and others at Delta — about 25,000 to 30,000 total, according to Stephen Gordon, president of District 143 of the union.

The union is handing out fliers and authorization cards to employees outside Atlanta's Hartsfield-Jackson International Airport, in a nearby Delta employee parking lot and outside Delta's reservations office. With authorization cards for at least 35 percent of employees it wants to represent, a union can file for an election.

"Delta has always been the most anti-union airline," said Gary Mobley, who is running the Atlanta campaign. "We're trying to write a new chapter where we're able to organize it."

His group of seven people working out of the Atlanta office is focused on Delta's ramp workers and customer service employees at the airport. But the organizing effort is no sure thing. The Transport Workers Union, for example, has tried unsuccessfully to organize Delta ramp workers in the past. And Delta management will be waging its own campaign to persuade employees of the benefits of remaining nonunion.

"We will continue to talk to employees and share our point of view about how our direct relationship that we've had with our work groups and our people has always served us well ... and benefited Delta's people over the years," said Mike Campbell, Delta's executive vice president of human resources, labor and communications.

The Machinists union also is passing out information to Delta employees in other places across the country, including Salt Lake City and New York.

"Our goal is to organize the Delta workers regardless of whether there's a merger or not," said Machinists union spokesman Joe Tiberi. He said efforts to organize Delta workers began in 2006, two years before the merger was announced.

The Aircraft Mechanics Fraternal Association also started a campaign in 2006 to organize Delta mechanics. AMFA went on a 15-month strike at Northwest that started in 2005 and lost the union many of its members at the carrier. Hundreds of other mechanics working at Northwest are replacement workers from the strike. Other mechanics are on furlough, but their time to be potentially called back to work expires Nov. 6.

With a much smaller maintenance operation, Northwest "put themselves in a position to easily merge with Delta because Delta does have the infrastructure and all that Northwest has to do is have a layoff at Northwest and eliminate all those replacement workers," said AMFA national director Steve MacFarlane. MacFarlane said AMFA's goal is still to file for an election.

Meanwhile, the National Mediation Board is seeking to revise its rules that govern union representation in an airline merger. It has proposed to add language saying the board would "exercise its discretion" and extend the representation of a union from employees of one carrier to both carriers only when there is "more than a substantial majority, as determined by the board."
