Delta Air Lines customer service agents overwhelmingly voted against unionization Tuesday, the latest blow to unions at the former Northwest Airlines.
Unions seeking to represent all of Delta's flight attendants, baggage handlers and technical operations workers have lost a series of votes this year, representing 56,000 Delta workers. Delta, the least unionized of the major U.S. airlines, said it would now be able to align the pay and benefits of former Northwest employees with those of longtime Delta workers.
Tuesday's vote, with 8,746 votes against the union to 3,772 in favor of it, nullifies the union contract for the International Association of Machinists and Aerospace Workers (IAM), which had represented former Northwest workers. About 81 percent of eligible workers voted.
Like the other rejected unions, the IAM accused Delta of "illegal interference" in Tuesday's union election, and said it plans to file charges to that effect with the National Mediation Board in Washington. A union representative did not return a call for comment.
The Association of Flight Attendants-CWA last month filed interference claims with the National Mediation Board in connection with its union election at Delta. The IAM also said it would present evidence that Delta interfered in other union elections.
Earlier this year, the board held that Delta had interfered with a union election involving flight simulator technicians, the IAM said. Delta said the National Mediation Board had found it in violation on only two of several interference complaints in that election.
The anti-union votes were aided by the fact that, in most cases, non-unionized Delta workers heavily outnumbered unionized former Northwest employees. In Tuesday's vote, non-union employee voters outnumbered union workers by more than two to one.
Tuesday's defeat came even though federal voting rules for union organizing efforts had been changed in the unions' favor. Instead of having to win a majority of all union members eligible to vote, a union had to win only a majority of those who actually voted. As a result, stay-at-home voters were no longer counted as "no" votes.
