About 25 students affiliated with the Progressive Student Labor Movement (PSLM) gathered in the Science Center arcade Friday to prevent a University official from removing a display posted as part of their Living Wage Campaign.

The students' protest ended successfully as their posters were allowed to stay up over the weekend, pending discussions today with the official, Science Center events coordinator John Mather.

According to the Science Center facilities contract for the event, the posters were supposed to remain up through next week.

The posters told the stories and struggles of anonymous Harvard workers, with the title "Harvard works because we do." The campaign is designed to promote PSLM's Living Wage Campaign.

Greg R. Halpern '99, a recent graduate and PSLM member who designed the posters, said the dispute began when Mather left a message on his answering machine Thursday night informing him that the Science Center posters would have to come down by 5 p.m. Friday.

According to Halpern, when he contacted Mather on Friday he was told that the contract he had for the event was invalid.

"Mather said that they had made a mistake in letting me sign it," Halpern said. Only current undergraduates can officially sign contracts for displays.

"We would have to take the posters down by 5p.m., or they would be taken down for us," he said.
