While organized labor made some headway in the second half of the twentieth century, a major setback was the failure of the national unions and the State Federation of Labor to prevent North Carolina from becoming a right-to-work state in 1947. Since the 1970s, a decline in employment and union membership in manufacturing industries has been partially offset by union growth among public employees (including police and fire personnel) and service employees. By the early twenty-first century, organizing activities increasingly focused on the state's agricultural and food-processing workers. A 1995 strike and union election by largely Guatemalan poultry processors at Morganton's Case Farms was one such effort that garnered regional and national attention. While workers voted to affiliate with the Laborers International Union of North America, Case Farms management refused to negotiate with the union, sparking labor strife that lasted through the end of the 1990s.
In the early 2000s, North Carolina remained among the least-unionized states in the nation. Total union membership at times has been estimated to be no more than 8 percent of the state's nonagricultural workforce, although the U.S. Department of Labor reported North Carolina union membership at only about 3.2 percent in the early twenty-first century.
