I support Graduate Students United in their demand for recognition as our graduate student worker union, and thank them for the essential contributions they have made and continue to make to our university. I stood in solidarity with them during the industrial action they recently undertook. I know that this action inevitably inconvenienced students, faculty, and staff, but believe that the responsibility in this case lies squarely with our administration and their refusal to recognize the democratic voice of our graduate student workers, a decision that is properly seen as part of a generally hostile attitude toward collective bargaining, and a pattern of favoring those who can afford to give this institution capital over those who can only afford to give it labor.
