A group of employees at Activision Blizzard studio have formed a union and are seeking its voluntary recognition.
The union, supported by the Communications Workers of America, represents 34 people in the quality assurance department at Raven Software.
In a statement Activision said, it was considering the matter.
Employees could also seek to hold an election supervised by the National Labor Relations Board (NLRB).
The company’s shares has been hammered in recent months and is facing multiple accusations of sexual harassment and misconduct.
Last week, Microsoft Corp announced plans to acquire the company.
Criticism of the company’s corporate culture has mounted in recent months, with workers even staging a walkout and circulating a petition calling for the removal of Chief Executive Bobby Kotick.
“Unionization has emerged as a goal for some, and workers in other parts of Activision Blizzard are also signing union cards”, said Jessica Gonzalez, a former Activision employee along with a current employee who spoke on condition of anonymity.
“I hope that we are able to serve as inspiration and to help guide other parts of Activision Blizzard … that want to follow in our footsteps,” said Onah Rongstad, a quality assurance tester at Raven.
In a statement Activision Blizzard said it is “carefully reviewing” the request for voluntary recognition. “While we believe that a direct relationship between the company and its team members delivers the strongest workforce opportunities, we deeply respect the rights of all employees under the law to make their own decisions about whether or not to join a union”.
“If Activision Blizzard does not voluntarily recognize the union, workers plan to seek to hold an election sponsored by the NLRB,” said Rongstad while adding, “Workers on Raven’s quality assurance team began striking in December after learning that 12 of their colleagues had been laid off”.
“By forming a union, the workers hope to gain more of a say in decision-making at the company as well as help set their working conditions. QA testers at Raven work up to 50- to 60-hour weeks when deadlines are looming,” said Rongstad.
