In the battle over the Employee Free Choice Act [3] (EFCA), which would make it easier for workers to join a union, "both the U.S. Chamber of Commerce [4] and the AFL-CIO [5] are focusing on grassroots outreach." Before the bill was introduced, "the Chamber launched the Workforce Freedom Airlift [6] program, a series of events that fly in local small business owners to Washington," to lobby against the bill. The first "airlift," on March 10, "brought in small business owners from Pennsylvania, Virginia, Nebraska, and Louisiana." Since July 2008, the Chamber has worked with Adfero Group on an anti-EFCA "social media effort," expanding "a virtual march on Washington [7] that was created the last time the bill went to Congress in 2007." It "allows users to register for the march as avatars and send an automatic letter to their elected officials through a Facebook [8] application." Meanwhile, the AFL-CIO is highlighting "YouTube videos [9] of workers sharing their support" of EFCA, and running "an online contest [10] that allows users to vote on the most outrageous statements from the opposition."
