eighteen-and-a-half-cent wage increase but little more. The UAW went along with GM in return for an ever-increasing packages of wage and benefit hikes through collective bargaining, with no help from the government. New leadership Walter Reuther won the election for president at the UAW's constitutional convention in 1946 and served until his death in an airplane accident in May 1970. Reuther led the union during one of the most prosperous periods for workers in U.S. history. Immediately after the war left-wing elements demanded "30–40": that is, a 30-hour week for 40 hours pay. Reuther rejected 30–40 and decided to concentrate on total annual wages, displaying a new corporatist mentality that accepted management's argument that shorter hours conflicted with wage increases and other job benefits and abandoning the old confrontational syndicalist position that shorter hours drove up wages and protected against unemployment. The UAW delivered contracts for his membership through negotiation. Reuther would pick one of the "Big three" automakers, and if it did not offer concessions, he would strike it and let the other two absorb its sales. Besides high hourly wage rates and paid vacations, in 1950 Reuther negotiated an industry first contract with General Motors known as the "Treaty of Detroit" (Fortune magazine) becoming known as Reuther's Treaty of Detroit. The UAW negotiated employer-funded pensions at Chrysler, medical insurance at GM, and in 1955 supplementary unemployment benefits at Ford. Many smaller suppliers followed suit with benefits. Reuther tried to negotiate lower automobile prices for the consumer with each contract, with limited success. An agreement on profit sharing with American Motors led nowhere, because profits were small at this minor player. The UAW expanded its scope to include workers in other major industries such as the aerospace and agricultural-implement industries. The UAW disaffiliated from the AFL–CIO on July 1, 1968, after Reuther and AFL–CIO President George Meany could not come to agreement on a wide range of policy issues or reforms to AFL–CIO governance. On July 24, 1968, just days after the UAW disaffiliation, Teamsters General President Frank Fitzsimmons and Reuther formed the Alliance for Labor Action as a new national trade union center to organize unorganized workers and pursue leftist political and social projects. Meany denounced the ALA as a dual union, although Reuther argued it was not. The Alliance's initial program was ambitious. Reuther's death in a plane crash on May 9, 1970, near Black Lake, Michigan,
