More than 500 Activision Blizzard employees have formed a union with the Communications Workers of America, just days after a union was formed at Bethesda Game Studios. Both studios have been acquired by Microsoft in recent years, benefiting from a labor neutrality agreement at the company. At Blizzard, the unionization push has resulted in two separate units, one consisting of World of Warcraft developers and one made up of QA testers.
