Pension reform "is essential to avoiding deep, immediate - and, yes, painful - cuts," not just in the coming budget but in spending over the next few years, Zogby said.
Asked where those cuts might occur in the budget for the next fiscal year, which begins July 1, he said the bulk of the year's pension costs is benefits paid to public school teachers.
"There will be some who will argue that because it's a public-school funding cost, that maybe it ought to be borne in other things in public education," the budget secretary said.
That stance is likely to define the battle over spending that will ensue in the Capitol once Corbett gives his budget speech before the legislature on Tuesday.
The governor told the Inquirer Editorial Board last week that he did not foresee cutting aid, as he has in previous years, for public schools or the state-related universities, Lincoln, Pennsylvania State, Pittsburgh, and Temple. But he said he would not rule out changing that scenario if legislators fought his yet-to-be-announced pension proposal.
Zogby added little detail Monday regarding that proposal. He reiterated that current retirees' pensions would not be touched and that the administration was not looking to change benefits already accrued by current employees, only their future benefits.
Asked how far administration officials were willing to push on pensions - were they prepared, for instance, to forgo timely passage of the state budget - Zogby was circumspect but he noted that in 2014, the governor and legislators alike are on the ballot.
"This is the year to deal with pension reform," he said. "I think if we don't do it this year, we are going to have some very difficult years ahead of us. And we are going to have to deal with it at a time that doesn't really lend itself to doing it the right way, [especially if] in an election year."
A harbinger of what awaits Zogby and Corbett came Monday from the state's largest teachers' union. Its spokesman said the administration was setting up a false fight, an either-or battle with little basis in reality. He said Corbett had other options, such as freezing tax cuts for businesses.
