Freelance casting assistants in New York and Los Angeles have unanimously voted to unionize with two Teamsters Locals.

In a National Labor Relations Board vote whose ballots were counted on Monday, 91 casting assistants employed by top studios supported unionizing with Teamsters Locals 399 and 817. The election took place between July 19 and Aug. 9, with the contest open to any casting assistants who had worked 15 days with a single major studio over the course of a year. Casting assistants employed on projects by Alliance of Motion Picture and Television Producer members as well as Netflix, which has a separate casting director contract with the Teamsters, were eligible to take part.

The Teamsters Local 399 estimates that the bargaining unit may ultimately include around 150-200 casting assistants.

This organizing win proves that casting in both Los Angeles and New York is by Teamsters. I am proud of not only the assistants in their fight to make improvements to their career and livelihood but also our 399 and 817 members that stepped up to support this group in their fight, Local 399 principal officer Lindsay Dougherty said in a statement.

The Hollywood Reporter has reached out to the AMPTP for comment.
