The International Alliance of Theatrical Stage Employees (IATSE) isn’t a company but rather a labor union. Established in 1893, it represents professionals in the entertainment industry, primarily in the U.S. and Canada. While not owned by a singular entity, as unions are collectively managed, its leadership comprises elected officials from its membership. IATSE’s members are diverse, spanning film, television, theater, and trade shows, among others. Key areas of operation include not just major entertainment hubs like Hollywood and Broadway but also local theaters and production facilities across North America.
