Nearly 1,900 Blizzard Entertainment workers ratified their first union contract with Microsoft after over two years of negotiations, securing protections for generative AI use, remote work, crediting, and layoffs. The four-to-five-year agreement covers three bargaining units and includes a 60-day notice period for layoffs, severance provisions, and a successorship clause ensuring terms survive if the company is sold. The contract requires human oversight of AI tools and mandates bargaining before implementing AI technology that materially impacts union employees' work.
