What strategies did both césar chávez and the ufwoc use to achieve their goals? how did they successfully apply these tactics?

Cesar Chavez and the United Farmer Workers used different forms of nonviolent protest in order to achieve their goals. For example, in 1965 workers who worked on grapes farm went on strike due to their poor pay and working conditions. This was known as the Delano grape strike. Along with strike, individuals also boycotted (aka refused to buy) the products. The goal in doing this would be to hurt the amount of profit individuals made of grapes. These tactics were used for 5 years, and resulted in a positive effect for the UFWOC, as they were able to gain their first written contract with the growers.

The answer would be advertising.
