The Teamsters union on Tuesday ramped up its effort to displace the unions representing ground workers at American Airlines and US Airways Group , which plan to merge this year and form the world's biggest airline.
The Teamsters said it filed with the U.S. National Mediation Board for an election to represent mechanics at AMR Corp's American Airlines, who are currently represented by the Transport Workers Union of America. Earlier this month, the Teamsters filed for an election for US Airways mechanics, seeking to displace the machinists union.
Should the National Mediation Board determine that 50 percent of the union members at US Airways and American Airlines favor the Teamsters, it can set representation elections. The Teamsters union declined to comment on how many signatures it had obtained from American mechanics.
