This study utilizes time-series data from 1897-2005 to explore the positive and negative effects of rivalry between labor unions. Utilizing econometric factors, it also investigates how competition from rival union federations and independent unions affects union density. Variables include counts of pro-labor and pro-management unfair labor practice cases adjudicated by the National Labor Relations Board, competitor union membership ratio and number ratio, the annual percentage change in union density, and the percentage change in the density of AFL/AFL-CIO membership. Other variables include the percentage of United States House members who belong to the Democratic Party, the percentage of popular votes in presidential elections that favored Socialist or Communist parties, core employment and unemployment, the consumer price index (CPI), and the labor union historical periods: Western Labor Union (WLU), Industrial Workers of the World (IWW), Trade Union Unity League (TUUL), Congress of Industrial Organizations (CIO), American Federation of Labor and Congress of Industrial Organizations (AFL-CIO), and Change to Win (CTW).
