Production assistants on CBS’ upcoming legal drama Cupertino have unanimously voted to unionize with LiUNA Local 724.

The vote, which concluded Wednesday, marks the first union election that the Production Assistants United movement, which is affiliated with the LiUNA Local, has won at a CBS Studios production. Out of 25 eligible production assistants, 13 voted to join LiUNA Local 724 in the National Labor Relations Board election, while the ballots of three were challenged.

“Our unanimous decision is a testament to the power of production assistants and the need for change in the entertainment industry. We are excited to come together and begin the work of negotiating our first contract,” the production assistants on the project said in a statement.

The Hollywood Reporter has reached out to CBS Studios for comment.

Set to premiere this fall, Cupertino follows a former lawyer for a start-up (Mike Colter) who, after being swindled by his former employer, opens up a law firm with another attorney to advocate for the little guy in disputes with tech titans. Despite the fact that it is set in Silicon Valley, the Robert and Michelle King-created show has been shooting its first season in New Jersey.
