For weeks now, striking graduate students affiliated with the United Auto Workers union have been disrupting classes at Harvard while the administration stands idly by. Non-tenure track faculty joined the strike on Tuesday, rallying to chants of “shut it down!” The “it” in question is the university.  At a faculty meeting on Tuesday, according to the Harvard Crimson, faculty members demanded a more forceful response to the mayhem. History of Science professor David S. Jones, whose students could not concentrate on a midterm exam that was interrupted by protesters chanting into a megaphone and blasting an air horn, beseeched administrators to “help faculty and students who remain committed to undergraduate education.”
