The graduate students were seeking a higher stipend, lower health-insurance costs, smaller classes, more teacher training and a procedure to air grievances.

Brown said she feared that some graduate students still would not get their teaching positions back. Conroy said that for some teaching assistants that question remained unresolved and that some could, indeed, lose their teaching appointments despite the strike's end.

Classes resumed Monday following winter break, and the undergraduates received their grade sheets.

For seniors, a prolonged strike could have affected their transcripts and their chances of getting into graduate schools.

"They should just get busy teaching," said Gus Kallergis, 21, a senior from Akron, Ohio. "The...strike has perverted the relationship that exists between professors and their graduate student teachers."

Jeff Glasser, 21, a senior from Montclair, J.J., said the graduate students' submission "shows an unlucky weakness" in the group's rank and file.

"They're willing to support GESO to a point, but they won't go all the way," he said.

Brown said the latest clash between the student group and the administration demonstrated "the lengths that Yale will go to to prevent unionization" and that it is essential the graduate students have a union.

Last week, 137 graduate students faculty and other supporters of the graduate students were arrested for blocking a street in demonstration over Yale's treatment of graduate students.

The student group also later filed a federal unfair labor practice complaint against Yale
