Other anti-union organizations have also made vocal contributions to anti-union discourse and union busting activities. The Citizens' Alliance was an employers' organization formed early in the 1900s specifically to fight trade unions. It worked with the NAM to strengthen anti-union movements in the early 20th century in the United States. The Council on Union Free Environment (CUE) had the specific mission of defeating President Carter's labor law reform bill that was designed to make union-organizing efforts more successful by, among other provisions, allowing for elections to occur within 15 days of filing a petition. The Labor Law Study Group, later called the Construction Users Anti-Inflation Roundtable, introduced dozens of labor law reform bills in the U.S. Congress, but their primary focus was repealing state and federal laws that established minimum wage standards on publicly funded projects. Associated Builders and Contractors (ABC) is the construction industry's voice and is funded chiefly by non-union builders and related businesses and promoted the "merit shop" which sought to pay each employee according to his qualification and performance. While the group insisted it was not anti-union, the system would preclude workers from exercising many of the worker-related benefits of a union.
