Why was the American federation of lador called the bread and butter?

The American Federation of Labor (AFL) was often referred to as the "bread and butter" union because it focused on practical, immediate issues affecting workers, such as wages, working conditions, and job security. This approach contrasted with more radical labor movements that sought broader social change. By emphasizing these fundamental economic concerns, the AFL aimed to improve the daily lives of its members, ensuring they could secure their basic needs. As a result, the term "bread and butter" symbolized the union's commitment to tangible benefits for workers.
