Group of Activision Blizzard employees votes to form the company's first union

Some workers at Activision Blizzard have officially unionized, marking the company's first union and the video game industry's most high-profile successful organizing effort.

A group of quality assurance employees at Raven Software, a gaming studio owned by Activision Blizzard (ATVI) that works on the company's popular "Call of Duty" game series, voted on Monday to form a union they are calling the Game Workers Alliance. The union will represent 28 workers, 19 of whom voted in favor of unionizing, according to the Communications Workers of America (CWA), which has been supporting the effort.

"Our biggest hope is that our union serves as inspiration for the growing movement of workers organizing at video game studios to create better games and build workplaces that reflect our values and empower all of us," members of the alliance said in a statement shared by CWA. "We look forward to working with management to positively shape our working conditions and the future of Activision Blizzard through a strong union contract," they added.
