And hundreds of farmworkers and their supporters have wrapped up a five-state, nine-day march in their latest effort to improve conditions at the fields and farms serving major food companies. The Coalition of Immokalee Workers’ “Now is the Time” march focused on urging the food giants Publix and Wendy’s to join the Fair Food Program, which ensures improved wages and working conditions for farmworkers in the companies’ supply chains. The march set off from Florida, reaching as far north as Ohio before returning home for an overnight vigil on Saturday outside a Publix store in the town of Lakeland.
