Communism, also known as a command system, is an economic system where the government owns most of the factors of production and decides the allocation of resources and what products and services will be provided. The most important originators of communist doctrine were Karl Marx and Frederick Engels.

When Filipino American farm workers initiated the Delano grape strike on September 8, 1965, to protest for higher wages, Chávez eagerly supported them. Six months later, Chávez and the NFWA led a strike of California grape pickers on the historic farmworkers march from Delano to the California state capitol in Sacramento for similar goals. The UFW encouraged all Americans to boycott table grapes as a show of support. The strike lasted five years and attracted national attention.
<span>In the early 1970s, the UFW organized strikes and boycotts—including the Salad Bowl strike, the largest farm worker strike in U.S. history—to protest for, and later win, higher wages for those farm workers who were working for grape and lettuce growers. The union also won passage of the California Agricultural Labor Relations Act, which gave collective bargaining rights to farm workers. During the 1980s, Chávez led a boycott to protest the use of toxic pesticides on grapes. Bumper stickers reading "NO GRAPES" and "UVAS NO" (the translation in Spanish) were widespread. He again fasted to draw public attention. UFW organizers believed that a reduction in produce sales by 15% was sufficient to wipe out the profit margin of the boycotted product. These strikes and boycotts generally ended with the signing of bargaining agreements. </span>
<span>Chávez undertook a number of spiritual fasts, regarding the act as “a personal spiritual transformation”. In 1968, he fasted for 25 days, promoting the principle of nonviolence. In 1970, Chávez began a fast of ‘thanksgiving and hope’ to prepare for pre-arranged civil disobedience by farm workers. Also in 1972, he fasted in response to Arizona’s passage of legislation that prohibited boycotts and strikes by farm workers during the harvest seasons. These fasts were influenced by the Catholic tradition of doing penance and by Gandhi’s fasts and emphasis of nonviolence.
He used boycotting as well</span>
