Members of the Writers Guild of America East (WGAE) and Writers Guild of America West (WGAW) at Sesame Workshop voted unanimously, with 100% participation, to authorize a strike if management does not agree to a fair new collective bargaining agreement before their current contract expires on April 19, 2024.
From what I understand, writers usually work under the Writer’s Guild. This report says 12.1% for the motion and sound recording industry as a whole.
