The 1930s led to a rise of labor unions in motion pictures as in other industries such as The Screen Actors Guild which was formed in 1933. Animators of Fleischer Studios went on strike in 1937 when Max Fleischer fired 15 employees, all who were a part of American Art-Union. The Fleischer strike was eventually solved by forming The Screen Cartoonists' Guild in 1938. The leader of the Guild was Herbert Sorrell who was described as a "tough left-winger", began a push and obtained contracts with Terrytoons, Walter Lantz Productions, Screen Gems, George Pal and MGM. Leon Schlesinger, whose Leon Schlesinger Productions produced the popular Looney Tunes/Merrie Melodies cartoons for Warner Bros., attempted a lockout, but soon gave in to the union and then asked, "What about Disney?".
