Almost three years after starting the bargaining process with Microsoft, quality assurance workers at two Blizzard locations have ratified a union contract. The agreement covers 60 workers at Blizzard Albany and Blizzard Austin.

The agreement includes guaranteed pay increases across the three years of the contract, assurances that workers will be given fair credits and recognition on games that ship, discrimination-free disability accommodations, restrictions on crunch (i.e. mandatory overtime) and “protection to immigrant workers from unfair discipline and loss of seniority while streamlining legal verification.” Stronger rules around the use of AI are included in the contract as well.

“At a time when layoffs are hitting our industry hard, today is another big step in building a better future for video game workers at every level,” Blizzard Albany quality analyst Brock Davis said in a statement. “For quality assurance testers, this contract provides us wages to live on, increased job security benefits and guardrails around artificial intelligence in the workplace.”

As with other unions in Microsoft’s game divisions, the Blizzard QA workers organized with the Communications Workers of America. This marks the third union agreement at Microsoft after ZeniMax and Raven Software workers ratified contracts last summer. Several other Blizzard divisions have unionized within the last year, including the cinematics team, Overwatch developers and a unit that works on Diablo.
