As it stands, negotiations on the issue in the legislature are bogged down in disagreements.
The governor backs a proposal that would only impact new employees, and would combine a traditional, defined-benefit pension with a 401(k)-style plan to provide a smaller benefit than current employees receive. It is expected to save the state more than $10 billion over 30 years.
As he spoke, Senators were preparing to consider changes to a $29.1 billion budget proposal passed Wednesday by the Republican-controlled House. That plan came in hundreds of millions of dollars below than Corbett's initial proposal, and hinges in part on $380 million projected to come from the sale of the state liquor system - a sale that's unlikely because it lacks widespread support.
Senate leaders have not ruled out new taxes - including on natural gas drilling - to help close a shortfall of at least $1.4 billion in the state budget for next year.
For his part, Corbett has said that if the legislature does not move on a pension bill, he will not even consider any new taxes.
Said Corbett: "I can't see today a budget coming to me real fast."
