Student workers at Grinnell College in Iowa have withdrawn plans to expand their union over fears that the NLRB, appointed by President Trump, would strike down their petition. The students worry that the board in its ruling could make sweeping changes that would threaten student unions across the country. The union, which covers only food service workers, had hoped to expand its representation to all student workers at the college. Grinnell administrators have fought the union's expansion plans, arguing that the union could jeopardize student's education by placing a barrier between students and faculty.
