The Union Behind the Curtain

IATSE (pronounced ‘eye-AHT-see’) is the acronym for the International Alliance of Theatrical Stage Employees, Moving Picture Technicians, Artists and Allied Crafts of the United States, Its Territories and Canada. It is the largest and most powerful labor union in the entertainment industry, representing over 170,000 ‘below-the-line’ workers. If you see a name in a film’s credits that isn’t a writer, director, producer, or actor, that person is very likely a member of an IATSE local.

IATSE’s members are the highly skilled artisans and technicians who are responsible for the physical creation of a film, television show, or live theatrical production. They are the hands-on craftspeople who build the sets, design the costumes, light the scenes, record the sound, and edit the final product.

A Federation of Specialized Locals

IATSE is not a single, monolithic union but an international alliance comprised of hundreds of local chapters, or ‘locals.’ Each local represents a specific, highly specialized craft or a particular geographic region. This structure allows for expert representation tailored to the unique needs and skills of each profession.

Some of the most prominent Hollywood-based IATSE locals include:
