Why did john ritter am joyce dewitt refuse to work with Suzanne somers?

John Ritter and Joyce DeWitt had a contentious relationship with Suzanne Somers during their time on "Three's Company" primarily due to Somers' demand for a significant salary increase, which they felt undermined the ensemble nature of the show. Their disagreement escalated when Somers sought to negotiate her contract independently, leading to tensions on set. Ultimately, Ritter and DeWitt were uncomfortable with her approach, which contributed to her departure from the series.
