— Graduate students who participated in the walk out defied Dean of the College John Boyer, who sent an e-mail on Wednesday asking that graduate students fulfill their instructional responsibilities instead of “walking out on [their] students.”

— The walkout began at 11:03 a.m. to symbolize the 1,103 votes cast by graduate students in the union election last fall, before GSU withdrew its union case to prevent a reversal of a national pro-union labor ruling.

— In a statement yesterday, the University reaffirmed its commitment to free expression, and said, “The American Federation of Teachers and American Association of University Professors voluntarily withdrew their election petition, and there is no union with legal status as the certified representative of any graduate teaching or research assistants at the University.”
