 The campaign is notable because of the extensive international pressure the USW brought to bear on Ravenswood and for the creative legal strategies the union employed.Most importantly, however, the Ravenswood effort showed that, properly undertaken and financed, a comprehensive campaign could put so much pressure on an employer that even recourse to permanent replacements could not defeat the union (as the tactic had at Hormel and International Paper).In 1993, UFCW undertook a comprehensive campaign in the food industry.
