The organizers of the boycott want Chicago public school students to skip the first day of class to protest the way schools are funded in Illinois.
But LULAC is asking the organizers to negotiate in Springfield, not in the classroom.
"Stop the nonsense and go. We voted for you, you're in the state legislature. Do your job while you're in there. Education is first, second and last," said Julie Santos, LULAC Council of Pilsen.
Santos says LULAC's mission is to keep the doors of opportunity open through education.
