Quality assurance developers at Raven Software have called off their strike as the group launches a campaign to form a union at the Call of Duty studio.

The ABK Workers Alliance social media page announced, "Pending the recognition of our union, the Raven QA strike has ended." The strike began in early December after a number of staffers were let go. A fundraiser on GoFundMe to support the striking workers has raised more than $370,000 USD.

Any unused money from the fundraiser will be put aside into a separate pool for future organizing or strike efforts, ABK Workers Alliance said on Twitter.
