A group of airline mechanics at United Airlines, displeased with the union that represents them, is asking members to switch to the International Brotherhood of Teamsters. The disgruntled union workers are part of the 3,000 United Airlines mechanics at the carrier's maintenance shop at San Francisco International Airport, where unrest stirred not long after the Aircraft Mechanics Fraternal Association (AMFA) was elected in mid-2003 to represent them. The airline industry was in deep economic decline, and the mechanics walked away from the International Association of Machinists and Aerospace Workers, their union home for 58 years.
