The Federation of Organized Trades and Labor Unions began in 1881 under the leadership of Samuel Gompers. Like the National Labor Union, it was a federation of different unions and did not directly enroll workers. Its original goals were to encourage the formation of trade unions and to obtain legislation,
such as prohibition of child labor, a national eight hour day, and exclusion of foreign contract workers. The Federation made some efforts to obtain favorable legislation, but had little success in organizing or chartering new unions. It came out in support of the proposal, traditionally attributed to Peter J. McGuire of the Carpenters Union, for a national Labor Day holiday on the first Monday in September, and threw itself behind the eight hour movement, which sought to limit the workday by either legislation or union organizing.
In 1886, as the relations between the trade union movement and the Knights of Labor worsened, McGuire and other union leaders called for a convention to be held at Columbus, Ohio on December 8. The Federation of Organized Trades and Labor Unions merged with the new organization, known as the American Federation of Labor or AFL, formed at that convention.[13]
The AFL was formed in large part because of the dissatisfaction of many trade union leaders with the Knights of Labor, an organization that contained many trade unions and that had played a leading role in some of the largest strikes of the era. The new AFL distinguished itself from the Knights by emphasizing the autonomy of each trade union affiliated with it and limiting membership to workers and organizations made up of workers, unlike the Knights which, because of its producerist focus, welcomed some who were not wage workers.
The AFL grew steadily in the late 19th century while the Knights all but disappeared. Although Gompers at first advocated something like industrial unionism, he retreated from that in the face of opposition from the craft unions that made up most of the AFL.
The unions of the AFL were composed primarily of skilled men; unskilled workers, African-Americans, and women were generally excluded. The AFL saw women as threatening the jobs of men, since they often worked for lower wages. The AFL provided little to no support for women's attempts to unionize.[14]
