The workers include parade performers, character actors and support staff at Disneyland and an adjacent theme park, Disney California Adventure. More than two-thirds of roughly 1,700 eligible workers signed the petition to seek an election through the National Labor Relations Board, the workers said, noting that a vote will likely be held in May or June,

Most of the more than 35,000 workers at the Disneyland Resort, which includes the theme parks, already have unions. Parade and character workers announced their plans to unionize in February under Actors’ Equity Association, which represents theatrical performers at Disney’s Florida theme parks.

Union membership has been on a decades-long decline in the United States, but organizations have seen growing public support in recent years amid high-profile contract negotiations involving Hollywood studios and Las Vegas hotels. The NLRB, which protects workers’ right to organize, reported more than 2,500 filings for union representation during the 2023 fiscal year, which was the highest number in eight years.

In California, Disney’s cleaning crews, food service workers, pyrotechnic specialists and security staff are already unionized. The company has faced allegations in recent years of not paying workers a livable wage for Southern California, despite raking in profits. Wage issues have even wound up in the courts.

Parade performers and character actors earn a base pay of $24.15 an hour, with premiums for different roles that can vary widely, workers said. Until January, the base pay was $20 an hour.
