"If Harvard wants to be a social partner and not just an institutional presence, it should step up to the plate and send a message that they are as concerned as we are," he said.

Galluccio said it was outrageous that the students had to gather in November to demonstrate for a cause they had first championed last spring. He said the University should have agreed to pay a living wage when the issue originally surfaced last March.

Wolf praised the crowd for showing their support despite the cold weather.

"If we have to come here in the middle of the winter and the snow is high, then we'll be here," she said.

After Wolf spoke, a contingent of 50 protesters entered Holyoke Center to visit the seventh-floor office of Kim A. Roberts, Harvard's director of labor and employee relations.

Roberts refused to meet with the demonstrators--the door to her office was blocked by Harvard University Police Department officers--so the students chanted and marched inside the corridor for about 10 minutes.

"I'm always amused at the lengths that administrators will go to to avoid talking to students," McKean said.

While some students demonstrated on the seventh floor, Schor addressed the crowd still assembled outside.
