30 Most Powerful Unions in America
Few things have been as important to the development of a strong middle class in America as the labor union. In their heyday, labor unions were an essential piece of the social fabric that helped ensure that workers could have a strong voice in getting paid fair wages, securing important benefits and ensuring safe working conditions. However, the days of organized labor wielding enormous influence are largely gone as union memberships continue to shrink in the face of an ever-shifting economy. From 1983 to 2015, union rolls shrank by nearly 3 million workers even as over 45 million more people joined the workforce, and the proportion of workers in a union was cut in half over that same period.
So, what does the face of American organized labor look like today? What unions still command the largest membership base, allowing them to influence public policy and pressure companies into making concessions?

More From GOBankingRates
Methodology: GOBankingRates looked at 73 labor unions within the United States in order to determine the 30 most powerful unions in America. GOBankingRates ranked the unions in terms of total members which was found using the Office of Labor-Management Standards’ (OLMS) union reports under Schedule 13 which tallies total union members. The union had to report the data to the OLMS in order to be considered for this list, thus some unions are not listed. Whether or not the union is affiliated with the American Federation of Labor and Congress of Industrial Organizations (AFL-CIO) was also provided as supplemental data. All data was collected and up to date as of Sept. 11, 2019.
