The Association of Pennsylvania State College and University Faculties announced on its website that its members went on strike at 5 a.m. since no agreement could be reached. The union represents more than 5,000 faculty and coaches across the state, and a walkout would likely halt classes mid-semester.
The union said late Tuesday night that the state had handed it its last, best offer and was done negotiating.
"We are headed to the picket lines, but even on the picket lines, our phones will be on, should the State System decide it doesn't want to abandon its students," APSCUF President Kenneth M. Mash said in a statement.
