GRINNELL, Iowa (AP) — Students at a private liberal arts college in central Iowa have voted overwhelmingly to expand a union for dining employees to include other student workers, but the college is asking a federal board to overturn the move. The Des Moines Register reports that the Tuesday vote would expand Grinnell College’s dining employees union to include more than 700 student workers across campus. The college has about 1,700 students.

Grinnell officials plan to ask the National Labor Relations Board to overturn the decision. The board’s decision could erode similar unionization efforts at other schools across the country.
A university spokeswoman says officials believe expanding the union would “undermine (the college’s) core educational mission and culture, impede learning and diminish educational opportunities for students.”
