What are the labor relations process and the structure of the modern labor movement?

"A labor union, such as the International Brotherhood of Teamsters, is an organization that represents workers in dealing with management over disputes involving wages, hours, and working conditions. The labor relations process that produces a union-management relationship consists of three phases: union organizing, negotiating a labor agreement, and administering the agreement. In phase one, a group of employees within a firm may form a union on their own, or an established union (United Auto Workers, for example) may target an employer and organize many of the firm’s workers into a local labor union. The second phase constitutes collective bargaining, which is the process of negotiating a labor agreement that provides for compensation and working arrangements mutually acceptable to the union and to management. Finally, the third phase of the labor relations process involves the daily administering of the labor agreement. This is done primarily through handling worker grievances and other workforce management problems that require interaction between managers and labor union officials.\n\nThe basic structure of the modern labor movement consists of three parts: local unions, national and international unions, and union federations. There are approximately 60,000 local unions, 75 national and international unions, and two federations. Union membership has been declining over the past three decades and is now half what it once was. The number of employed union members has declined by 2.9 million since 1983, the first year union statistics were reported. In 1983, union membership was 20.1 percent of workers, with 17.7 million union workers. In 2017, membership declined to 10.7 percent of workers, with 14.8 million members.\n\nA local union is a branch or unit of a national union that represents workers at a specific plant or over a specific geographic area. Local 276 of the United Auto Workers represents assembly employees at the General Motors plant in Arlington, Texas. A local union (in conformance with its national union rules) determines the number of local union officers, procedures for electing officers, the schedule of local meetings, financial arrangements with the national organization, and the local’s role in negotiating labor agreements. The three main functions of the local union are collective bargaining, worker relations and membership services, and community and political activities. Collective bargaining takes place every three or four years. Local union officers and shop stewards in the plant oversee labor relations on a day-to-day basis. A shop steward is an elected union official who represents union members to management when workers have complaints. For most union members, his or her primary contact with the union is through union officials at the local level.\n\nA national union can range in size from a few thousand members (Screen Actors Guild) to more than a million members (Teamsters). A national union may have a few to as many as several hundred local unions. The number of national unions has steadily declined since the early twentieth century. Much of this decline has resulted from union mergers. In 1999, for example, the United Papermakers International Union (UPICU) and the Oil, Chemical and Atomic Workers Union (OCAW) agreed to merge under the new name of PACE, or Paper, Allied-Industrial, Chemical and Energy International Union. PACE has about 245,000 members.\n\nFor 50 years, one union federation (the American Federation of Labor-Congress of Industrial Organization, or AFL-CIO) dominated the American labor movement. A federation is a collection of unions banded together to further organizing, public relations, political, and other mutually-agreed-upon purposes of the member unions. In the summer of 2005, several unions (Teamsters, Service Employees International Union, Laborers’ International Union, United Farm Workers, Carpenters and Joiners, Unite Here, and the United Food and Commercial Workers Union) split from the AFL-CIO and formed a new federation named the Change to Win Coalition. The new federation and its member unions represent more than 5.5 million union members. Change to Win Coalition member unions left the AFL-CIO over leadership disagreements and ineffective organizing strategies of the AFL-CIO; one of its primary goals is to strengthen union-organizing drives and reverse the decline in union membership."
