The ZeniMax Workers United union has reached a "tentative" labour agreement with Microsoft. 

Bloomberg reports that the deal includes a 13.5 per cent increase in wages for all staff from July 1st. That's on top of protections against arbitrary termination, some limitations on how Microsoft can use artificial intelligence tools and guarantees that quality assurance workers will be credited on the games they worked on. 

The Communications Workers of America (CWA) has also said that there will be new minimum salaries for staff. 

“Our first contract is an invitation for video game professionals everywhere to take action,” ZeniMax employee Jessee Leese told Bloomberg. 

”We’re the ones who make these games, and we’ll be the ones to set new standards for fair treatment.”

In a statement, a Microsoft rep added: “The tentative agreement represents a meaningful step forward and reflects a shared commitment to constructive dialogue and a common goal of fostering a positive workplace." 

This news comes over two years after ZeniMax Workers United was first formed. In April of this year, the union voted to strike amid claims that Microsoft was dragging its heels on its worker contract.
