Was there any animosity between Shirley and the producers of Laverne and Shirley?

Yes, there was animosity between Shirley and the producers of Laverne and Shirley. The show, which starred Penny Marshall and Cindy Williams, ran from 1976 to 1983. According to the book, Laverne & Shirley: A Behind-the-Scenes History of the Classic Show, Shirley was often at odds with the producers over her wages and her character. Marshall and Williams were given raises after the first season and Shirley was not, which created a rift between her and the producers. Shirley also wanted her character to become more involved in the show’s storylines, but the producers refused. This led to tensions between Shirley and the production team, and caused her to quit the show in 1982. Though Shirley later returned to the show, the animosity between her and the producers was an undeniable part of the show’s history.
