The International Association of Machinists and Aerospace Workers said Monday that US Airways mechanics and related employees voted overwhelmingly to retain the IAM as their bargaining representative.
The IAM said 1,903 members, or 58 percent of all votes cast, preferred the IAM, to 1,418 votes for the International Brotherhood of Teamsters, or 42 percent.
"This victory marks an important milestone for the Mechanic and Related group at US Airways," IAM Transportation vice president Sito Pantoja said in the IAM's announcement.
"By voting for the Machinists union, our members safeguarded their pensions and seniority heading into the merger with American Airlines while rejecting the empty promises of an organization with a history of corruption," Pantoja said.
While the Teamsters appear to have lost the US Airways campaign, they still have a similar effort underway at American Airlines. American's mechanics and related employees are currently represented by the Transport Workers Union.
The TWU filed affidavits from two people who were involved in the Teamsters efforts to say they had heard of signature forging going on by organizers. The Teamsters have asked to have until Aug. 23 to respond to the accusations.
Here's the count from the National Mediation Board:
