The faculty at UIC has voted to strike again.
They plan to start picketing April 23, unless an agreement can be reached with the administration before then.
Two more bargaining sessions are scheduled for next week.
Both sides are at odds over pay and promotion opportunities for full-time faculty who are non-tenured.
The faculty went on strike for two days in February.
No end date has been set, if they strike again.
Faculty members have not had a contract since unionizing in 2012.
