Hawaii Governor David Ige, a Democrat, on Monday announced that he would veto legislation that would permit graduate students in the University of Hawaii System to unionize. In a statement, he said: “Our administration appreciates the contributions graduate students make throughout the university system. Their valid concerns can and should be addressed internally through Board of Regents policy followed by a commitment from the university administration to implement such policy. We strongly encourage this option rather than amending state collective bargaining laws that govern management and employee relations.”
