Blizzard Workers Ratify First Union Contract with Microsoft
Nearly 1,900 Blizzard employees have voted to ratify their first union contract with Microsoft, establishing new protections around AI use, layoffs

Blizzard Entertainment has ratified its first union contract with parent company Microsoft. The deal, covering just under 1,900 workers, was approved by a workforce vote and concludes over two years of negotiations.
The agreement introduces key protections concerning generative AI, crediting, remote work, and layoff procedures. The contract's duration is set for four to five years, depending on the specific bargaining group.
New Contract Protections and Structure
The ratified contract establishes significant new terms for Blizzard's unionized employees. It mandates a 60-day notice period for layoffs, or pay in lieu of notice. Severance is set at one week of pay for every six months worked, and employees gain 14 months of recall rights. A successorship clause ensures the agreement remains valid even if Blizzard is sold to another company.
Blizzard's previously separate unions have been consolidated into three main bargaining units. The new structure organizes workers by their game and functional teams.
| Bargaining Unit | Coverage Areas |
|---|---|
| Unit 1 | World of Warcraft, Blizzard QA, Hearthstone |
| Unit 2 | Platform & Technology, Customer Support, Localization, Story & Franchise Development |
| Unit 3 | Diablo, Overwatch |
AI Guidelines and Crediting Rules
The contract directly addresses the use of artificial intelligence in game development. It states that while AI tools "may be useful in the game development process to support human judgment and creativity," all AI-assisted workflows must remain under appropriate human control and review. The agreement requires bargaining before implementing any AI technology that would materially impact union employees' work.
Crediting rules are also solidified. The contract requires that all current and former staff be listed by name on every title they contributed to, ensuring proper recognition for their work.
Remote Work and Management Response
Remote work policies are defined within the new agreement. It designates certain roles as hybrid while also providing employees a formal route to apply for fully remote status. This offers clearer guidelines for work location flexibility.
In a statement, Blizzard president Johanna Faries acknowledged the process. "We appreciate the dedication and engagement of our represented employees and the bargaining committees throughout this process," Faries said. She called the ratification a "significant milestone" reflecting a shared commitment to supporting teams and players.
Contrasting Union Developments at Activision
This development at Blizzard stands in contrast to events at another Activision studio. Candy Crush developer King has reportedly rejected a collective bargaining agreement with Swedish trade unions Unionen and Sveriges Ingenjörer. Several Microsoft subsidiaries have unionized since 2022, with Raven Software becoming the first major video game union in the United States.
