In a stunning move that could change the nature of college athletics, football players at Northwestern University filed a petition to unionize Tuesday morning. The players are seeking collective bargaining rights with the National Labor Relations Board. Ramogia Huma, president of the National College Players Association, submitted paperwork including signed union cards to the NLRB. Huma said he was approached by Northwestern quarterback Kain Colter last spring, asking for help to give players representation. If approved by the NLRB, the College Athletes Players Association would not receive union dues from players.
