But negotiations on that issue - among others - have been bogged down in disagreements, and the likelihood of passing a 2014-15 spending plan by Monday night remained unclear.
Late Thursday, the Senate Appropriations Committee passed the $29.1 billion spending plan that the House sent over Wednesday.
That proposal - one crafted by House Republicans and derided by Democrats - was hundreds of millions of dollars below the spending goal Corbett outlined earlier this year. It also had little chance of surviving in its current form, because it included no tax increases but depends on, among other things, $380 million projected to come from the sale of the state liquor system - a sale that lacks widespread support.
Negotiations on changes to the plan are expected to intensify in the coming days. Many in the GOP-controlled Senate have signaled that they wanted to tap new sources of revenue - a hike in the cigarette tax and a new gas-extraction tax have been discussed - to help plug a state budget hole of at least $1.4 billion.
But neither chamber has addressed Corbett's demand to change the retirement-system funding.
The governor backs a proposal that would affect only 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.
For his part, Corbett has said that if the legislature did not move on a pension bill, he would not even consider any new taxes.
Said the governor: "I can't see today a budget coming to me real fast."
He and lawmakers weren't the only ones wrangling over the budget. A small group of activists seeking more money for Pennsylvania's public schools staged a sit-in outside Corbett's office. An organizer said similar demonstrations were planned in and around the state Capitol in the days ahead.
