The American Federation of Musicians (AFM) is the largest musicians union in the United States. The AFM represents over 80,000 professional musicians and has locals in every major city in the country. The AFM negotiates contracts with employers in a variety of industries, including the recording industry, the live music industry, and the film and television industry.
Other major musicians unions in the United States include the International Association of Machinists and Aerospace Workers (IAMAW), which represents musicians who work in the recording industry, and the Screen Actors Guild (SAG), which represents actors, singers, and other performers who work in the film and television industry.
Musicians unions play an important role in protecting the rights of professional musicians. By negotiating contracts with employers, musicians unions ensure that musicians are paid fairly for their work. They also provide legal assistance to their members and offer a variety of other services that help musicians to succeed in their careers.
