Culver City, California - Unsung workers who make movie superheroes fly and lightsabers crackle are turning to labor unions as relentless demand for content turns dream jobs into grueling routines.

A union trend that started at an independent game studio last year is gaining momentum as video streaming services vie for subscribers and video game makers push to keep players engaged.

The latest moves come from visual effects (VFX) crews at Marvel Studios and Walt Disney Pictures, according to labor organizers who represent behind-the-scenes workers in entertainment.

Marvel Studios’ VFX workers voted unanimously to unionize with the International Alliance of Theatrical Stage Employees (IATSE), the union announced Wednesday, calling it a historic and "significant milestone." It marks the first time a unit of solely VFX workers have unionized with the group, and is the first union of its kind at a major movie studio.

Labor organizers at IATSE see the effort as a major shift in a job with increased workloads and tight deadlines that has been largely non-union since VFX was revolutionized by Star Wars in the 1970s.

Visual effects crews at Walt Disney Pictures are voting this month whether to unionize, with results expected October 2.

Following the election, the next step for the union is to engage in collective bargaining negotiations with the employer to draft a contract addressing the needs of the represented workers, according to IATSE.

"We are witnessing an unprecedented wave of solidarity that's breaking down old barriers in the industry and proving we're all in this fight together," said IATSE International President Matthew Loeb.

"Entertainment workers everywhere are sticking up for each other's rights, that's what our movement is all about."

The rash of organizing comes as Hollywood is in the throes of shutdown and strike brought on by unionized writers and actors over pay and concerns about the use of artificial intelligence (AI).

Competition between streaming television titans Amazon, Apple, and Netflix has ramped up demand for shows, almost all of which involve visual effects these days, IATSE organizer Mark Patch told AFP.

"Without VFX, you wouldn't have a lightsaber; you wouldn't have Avengers flying around," Patch said. "We love this work, but we need health care; we need to be paid overtime, we need to have meal breaks."

It is common for VFX workers to put in 15-hour-plus days, even sleeping under desks while facing production deadlines, according to Patch.

Video game industry workers have long complained of similar grueling schedules during crunch times to make release dates.

Employees in studios are increasingly seeking solidarity to improve working conditions, according to IATSE international representative Chrissy Fellmeth. Video game worker pay and benefits have stagnated in the multi-billion-dollar industry, while the speed of releases has accelerated along with demand for updates, Fellmeth told AFP. And with games rushed out the door, studio workers have to scramble afterward to fix software bugs.

People working behind the scenes in video games typically last about seven years before changing careers to other tech sectors, according to Fellmeth.

"They tend to leave for greener pastures," Fellmeth said. "Even though they love working in games, it turns out to be way too difficult."

Game studio Workinman Interactive in New York state, which boasts clients including Nintendo and Disney, last month saw the start of a unionizing effort according to the IATSE.

"Writers and the actors being on strike have brought the idea of organizing to a lot of people's attention," Fellmeth said. "And that absolutely includes game workers."
