Food service and custodial workers plan a three-day strike this week at the University of Illinois at Urbana-Champaign, The Chicago Tribune reported. The workers, members of the Service Employees International Union Local 73, are frustrated by what they see as a lack of progress in negotiating a contract. The union predicted significant disruptions to food service this week, while the university vowed that it would provide hot meals and would minimize disruption by reassigning non-striking workers.
