That's what Purdue's treasurer Al Diaz said Wednesday in the wake of the University of Illinois announcing more than 11,000 employees would be required to take unpaid days off, starting next month. "I do not anticipate the need at this point to look at it any more seriously. It is an option that is available to use," Diaz said. "But University of Illinois (is) really dealing with a serious cash flow problem. We are clearly not in that situation."
