Marvit and Schriever wrote about the history of members-only unions in the United States, and how the model fell into near-obscurity after the passage of the
National Labor Relations Act of 1935. The writers covered a number of examples of minority unions, including the Texas Workers Alliance (an independent local in San Antonio, Texas) and CAAMWU of
United Electrical workers in
Nash County, North Carolina. A more recent example of a minority union is
UAW Local 42, which was formed in July 2014 at the
Volkswagen Chattanooga Assembly Plant in
Chattanooga, Tennessee. Despite a failed unionization vote at the plant,
Volkswagen recognizes members who have joined the local. After the close vote against the UAW, Volkswagen announced a new policy allowing groups representing at least 15% of the workforce to participate in meetings, with higher access tiers for groups representing 30% and 45% of employees. This prompted anti-UAW workers who opposed the first vote to form a rival union, the American Council of Employees. In December, 2014 the UAW was certified as representing more than 45% of employees. ==References==
