After years of impasse, one of the nation's largest tomato growers has made peace with the Coalition of Immokalee Workers...Pacific Tomato Growers [part of Sunripe Produce] pledged to improve its working conditions and pay harvesters a penny more per pound...The agreement, in effect today, is the first forged directly between the 4,000-member grass-roots group and a grower... Some...improvements...[include] shade in the fields,...health and safety programs, worker-to-worker education and a way to resolve complaints...Pacific's history with the group had been troubled...: In 2008, members of Immokalee's Navarrete family went to federal prison for enslaving 12 workers, whom they brought to work in Pacific's fields, as well as Six L's...The deal is just a first step but one that can lead "a model for generations of farmworkers and farmers to come," said the coalition's Lucas Benitez.
