Many of the speakers at Saturday's rally denounced the committee's finding.

Galluccio called on Harvard to follow the lead of the City Council, which unanimously passed a bill requiring all city employees to be paid a living wage.

"Show me the partnership, show me the hand, reach out to the city of Cambridge," Galluccio said. "We respected your committee process [but] we're here to say, Harvard University, you missed the point."

Decker said the University must increase the consumer power of its workers--something she said the report's recommendations would not.

"People cannot pay the rent with a GED course, with a library pass, with a museum pass," she said, referring to Harvard's plan to expand access to job training and campus facilities.

Affleck and Damon agreed to appear on Saturday at Decker's request, though the actors were already in Boston this weekend for an American Repertory Theatre event at the Four Seasons Hotel.

Both Decker and Damon graduated from Cambridge Rindge and Latin School in 1988, and Decker played Little League with Affleck, two years her junior.

She said the actors "jumped at the chance" to speak on behalf of the living wage campaign.
