Quality assurance workers at Activision Blizzard subsidiary unionize, a first at a major US gaming company

— A small group of quality assurance workers at an Activision Blizzard-owned game studio have unionized, marking the arrival of the first labor union at a major U.S. gaming company. The workers at Raven Software, which is a Wisconsin subsidiary of Activision, voted to form the union Game Workers Alliance with the Communications Workers of America. Nineteen workers voted in favor of the union, with three voting against, the National Labor Relations Board tallied Monday. Two additional challenged ballots were uncounted, but do not change the outcome.
