Activision Blizzard is converting all of its temporary and contract quality assurance workers in the US to full-time employees starting on July 1st. Many of the 1,100 workers will receive a pay raise — the minimum hourly rate is going up to $20 per hour as of April 17th. As permanent employees, the workers will receive benefits and can participate in a bonus plan.

The company says bringing those workers on board as staff will bolster its development resources and increase its number of full-time employees by 25 percent. It recently converted nearly 500 other temp and contract roles across its studios to full-time positions.

The move comes in the wake of a unionization drive spearheaded by QA team members at Raven Software. Workers from across Activision Blizzard staged a walkout in December after some Raven QA contractors were laid off. The following month, QA workers at the studio announced their intention to unionize, which would make them members of the first union at a AAA gaming company in North America.

Activision declined to voluntarily recognize the Game Workers Alliance union and shuffled some people to other departments. Executives also tried to convince workers not to form a union by questioning the benefits of organizing. Nevertheless, the Raven QA workers pressed forward with their plans and have filed for a union election through the National Labor Relations Board.

“Whether Raven workers choose to unionize has nothing to do with the salary increases elsewhere for Activision’s QA workers," an Activision Blizzard spokesperson told Bloomberg. The spokesperson added that Raven workers won't be eligible for the pay initiatives “due to legal obligations under the National Labor Relations Act.”

Microsoft, which has agreed a deal to buy the company for $68.7 billion, said last month it respected the right of Activision Blizzard employees "to choose whether to be represented by a labor organization and we will honor those decisions."
