But Harvard University is making no promises regarding the demands.

"This particular letter raises a number of issues that I think [Rudenstine] will want to respond to or have me respond to," said Allan A. Ryan, Jr., an attorney in the University's Office of the General Counsel who has served as Harvard's chief negotiator on this issue.

"But the date of March 8 is just a couple of days before the next Ivy meeting on this, so it may not be by that deadline," he added.

According to Ryan, the University is unlikely to negotiate a separate agreement on labor policies with PSLM until the Ivy League schools decide whether to take some sort of uniform action on the issue.

And he is non-commital about students' specific demands.

"Students have changed my thinking and [Rudenstine]'s thinking on some issues," he said. "Whether they will change it on every issue they want to change it, we'll have to wait and see."

But while Ryan stressed that students have been included in negotiations, PSLM members said they are being ignored.

Shuldiner said the University scrapped a year's worth of collaboration between Harvard and PSLM when other Ivy League schools decided they wanted to create a shared code.
