(Reuters) -Quality assurance workers at Blizzard Albany, a unit of games developer Activision Blizzard Inc, on Tuesday announced the formation of a union and have filed for union representation with the labor board, a statement from the workers said.

The Blizzard Albany workers are the second group of Activision Blizzard workers to form a union at the company.

In June, quality assurance workers at Activision's Raven Software studio in Wisconsin became the first union to be officially recognized at Activision Blizzard. (https://reut.rs/3zhXeOr)

"We believe that a direct relationship between the company and its employees is the most productive relationship. The company will be publicly and formally providing a response to the petition to the National Labor Relations Board," a spokesperson from Activision Blizzard said in an emailed statement.

Microsoft, which is in the process of acquiring Activision Blizzard, last month entered into a labor neutrality agreement with Communications Workers of America (CWA). This means that if the deal culminates, Microsoft will allow unionization of workers at the firm.
