On June 25, the San Francisco Board of Supervisors unanimously endorsed the United Farm Workers's boycott of Chiquita bananas and non-union iceberg lettuce.
Agricultural strikes are different than strikes in industry.
Even thought the UFW has signed many contracts with growers. Even after passage of California's historic Agricultural Labor Relations Act in 1975. The law now deals pretty effectively with growers who deny farm workers their rights during union elections or organizing campaigns. It is less vigorous in protecting workers from growers' strikebreaking tactics. The growers unilaterally declared an impasse in the talks and broke off negotiations.
