In a win for Ithaca College’s embattled adjunct faculty union, the American Arbitration Association said last week Ithaca wrongly disciplined Tom Schneller, part-time professor of music, for engaging in protected union activity. Ithaca recently announced heavy cuts to untenured faculty that threaten to decimate union ranks. In May, worried about potential layoffs, Schneller wrote a memo to full-time faculty colleagues called “Solidarity in a Time of Crisis: A Plea from Your Contingent Colleagues” and posted it to a virtual Ithaca message board.
