Recalling the times when I filled in without additional compensation for a colleague who was ill, the cynic in me says that, for all their political correctness, Columbia University faculty members can be had for a price as strike-breakers. If, in fact, graduate student instructors are"apprentices," as the University maintains, why would the University be willing to pay regular faculty additional money to do what they are contractually obliged to do, which is to teach? The University appears to be willing to pay a very heavy price to maintain an exploitative system and its faculty willing, for a price, to maintain a system with heavy benefits at the top. It is too early to know how many graduate student instructors have gone on strike. The strike has not yet disrupted classes to the extent of closing down the campus.
