Negotiations continue between the Pennsylvania State System of Higher Education's team and members of the APSCUF union.
The two sides are trying to hammer out a contract agreement.
The union has been working without one since June 2015 and has voted to authorize a strike.
Both sides are trying to come to an agreement on pay, health care changes and other items.
Officials said they'll continue meeting through Wednesday of this week, with additional sessions to come as needed.
