Pennsylvania's state-owned universities and its faculty union did not agree on a new contract proposal during their final negotiating session before the start of the spring semester.
Dr. Steve Hicks, president of the Association of Pennsylvania State College and University Faculties, said negotiators met for approximately six hours Wednesday but made no substantial progress.
The next meeting is scheduled for February 1.
Union members have been working without a contract since June 2011.
They have authorized their leadership to call a strike, but Hicks said the union would only consider a strike as a last resort.
