In 2009 a provision was added to the Federal Aviation Administration Reauthorization Act that would have changed the conditions under which some of FedEx Corporation's employees could unionize. FedEx referred to these provisions as the "Brown Bailout". Overview The argument between FedEx on the one hand and UPS and the International Brotherhood of Teamsters union on the other is over which labor act FedEx's non-airline personnel should be covered under, the National Labor Relations Act (NLRA) or the Railway Labor Act (RLA): under the NLRA, workers are able to unionize locally, on a site-by-site basis; under the RLA, workers must unionize nationally, which is more challenging and tends to keep rates of unionized workers low. As of June 2010, The NLRA covers UPS's non-airline workers, and the RLA all of its airline workers; a large number of UPS drivers, package handlers and clerks are represented by the International Brotherhood of Teamsters. Yet, all FedEx personnel, including those working on railways and other modes of ground transport, are covered under the RLA, which requires them to unionize nationally. If the provisions were passed, FedEx's non-airline personnel would be able to unionize more easily, because they would be covered under the NLRA. According to the Memphis-based company, this change could also "expose [its] customers at any time to local work stoppages that interrupt the flow of their time-sensitive, high-value shipments”. The International Brotherhood of Teamsters has counter-attacked with its own web campaign, "FedEx drivers aren't pilots", insisting on the fact that the NLRA, not the RLA, should apply to FedEx's ground personnel. Controversial use of the term 'bailout' The term 'Brown Bailout' refers to the provision that UPS has lobbied to have put into the $34.5 billion Federal Aviation Administration Reauthorization Act (H.R. 915) voted on by the United States House of Representatives in May 2009 and by the United States Senate in March 2010. The term was coined in FedEx's large online advertising campaign against UPS and the International Brotherhood of Teamsters; it seeks to emphasize the idea that changing FedEx's personnel statute would be equivalent to giving UPS a 'bailout'. However, independent observers have strongly criticized FedEx's wording, claiming that it was "an abuse of the term". Steve Centrillo, a marketing consultant quoted by the New York Times, described the use of the word 'bailout' as "the most questionably ethical thing on the [Brown Bailout] site". Quoted in the same
