The president of Eastern Illinois University says the $12.5 million the school receives in stopgap state funding won't be enough to get it through the summer.
EIU President David Glassman says the school will be "challenged" to make payroll for late July and early August and says future layoffs may be necessary.
The school is receiving about $12.5 million as part of a measure Illinois lawmakers approved earlier this month.
Lawmakers are amid a standoff over a full state budget.
EIU officials say the school asked for $24 million to $28 million.
EIU has lost 413 employees since layoffs started about a year ago.
The school has stopped hiring, postponed construction projects and restricted travel and purchases.
