Si se puede means:
Sí, se puede (Spanish for "Yes, it is possible" or, roughly, "Yes, it can be done"[1]) is the motto of the United Farm Workers. In 1972, during Cesar Chavez's 24 day fast in Phoenix, Arizona, he and UFW's co-founder, Dolores Huerta, came up with the slogan.[1]
The phrase has been widely adopted by other labor unions and civil rights organizations and drew widespread political and media attention as a rallying cry during the 2006 U.S. immigration reform protests.
