Nearly 1,900 Blizzard Entertainment workers ratified their first union contract with Microsoft after over two years of bargaining, securing protections on generative AI, crediting, remote work, and layoffs while consolidating multiple smaller unions into three larger bargaining units. The contract includes provisions requiring human control over AI implementation, employee crediting in games, hybrid and remote work options, 60-day layoff notice periods, and successorship guarantees lasting 4-5 years.
