When George Lucas first created Star Wars, he used non-union workers to make the visual effects-heavy film quickly.

But decades later, visual effects (VFX) workers are still non-union, leading to rampant abuse and turnover across the industry.

VFX workers are often some of the only workers on set without union protections. That’s finally about to change.

VFX workers at Disney and Marvel just voted to unionize with the International Alliance of Theatrical and Stage Employees (IATSE), becoming the first in the U.S. to do so in the industry’s history.
