In response to the financial crisis, Disney and his brother Roy started the company's first public stock offering in 1940, and implemented heavy salary cuts. The latter measure, and Disney's sometimes high-handed and insensitive manner of dealing with staff, led to a 1941 animators' strike which lasted five weeks. While a federal mediator from the National Labor Relations Board negotiated with the two sides, Disney accepted an offer from the Office of the Coordinator of Inter-American Affairs to make a goodwill trip to South America, ensuring he was absent during a resolution he knew would be unfavorable to the studio. As a result of the strikeand the financial state of the companyseveral animators left the studio, and Disney's relationship with other members of staff was permanently strained as a result. The strike temporarily interrupted the studio's next production, "Dumbo" (1941), which Disney produced in a simple and inexpensive manner; the film received a positive reaction from audiences and critics alike.
