For the last four decades, collective action in the ever-growing $138 billion game industry has been nearly nonexistent, despite the fact that workers are regularly subjected to exploitation in the form of 100-hour work weeks during “crunch time,” or sexist corporate cultures. While the characters they’re creating are regularly confronting bosses, the real-life video game workers themselves haven’t.

That changed on Monday when an estimated two hundred employees of Riot Games, the developer of the popular “League of Legends” PC game, marched out of their Los Angeles office to an on-site parking lot to picket management’s private arbitration policy and call out what they describe as a sexist and nepotistic environment.

“Sexual discrimination and harassment is an issue at Riot and a larger issue in the video game industry,” said Jocelyn Monahan, a social-listening strategist at Riot and one of the walkout’s organizers. “This is not an uncommon story, we’re just one of the first big companies to have an article about it that sparked this movement.”
