Is the stage actors union same as technical crews union?

The stage actors union is not the same as the technical crews union. The International Alliance of Theatrical Stage Employees (IATSE) represents approximately 150,000 technicians, artisans and craftspeople in the entertainment industry, including stagehands, lighting designers, sound engineers and other behind-the-scenes workers. The Actors' Equity Association (AEA) is the union representing actors and stage managers working on the stage.
