The union adopted the principles of non-violence championed by Mahatma Gandhi and Dr. Martin Luther King, Jr Chavez used fasts both as means of drawing public attention to the union's cause and to assert control over an often unruly union.
The union was poised to launch its next major campaign in the orange fields in 1973 when a deal between the International Brotherhood of Teamsters and the growers nearly destroyed it. The growers signed "sweetheart contracts" giving the Teamsters the right to represent the workers who had been members of the UFW, even though these workers had, for the most part, never asked for Teamster representation.
The UFW responded with strikes, lawsuits and boycotts. The union struggled to regain the members it had lost in the lettuce field; it never fully recovered its strength in grapes, due in some part to incompetent management of the hiring halls it had established that seemed to favor some workers over others.
The battles in the fields became violent, with a number of UFW members killed on the picket line. The violence led the state in 1975 to try to find a solution for these problems by creating an administrative agency, the Agricultural Labor Relations Board, to enforce a law modeled on the National Labor Relations Act that would channel these disputes into more peaceful forms.
Now, thirty years later, the union still works to organize California farm workers. The ALRB has been a disappointment to the union, since it has often operated slowly, when it functioned at all.
