Machinists union officials expect to receive Hawker Beechcraft's final contract offer today.
The union presented a counterproposal to the company on Monday.
Machinists spokesman Bob Wood declined to say how talks are going.
Members of Machinists Local Lodge 733 are scheduled to vote Saturday at the Kansas Coliseum Pavilion on whether to accept the company's offer. Doors will open at 9 a.m. A meeting to explain the offer and answer questions will begin at 10 a.m. Polls will close at 1:30 p.m.
Ratification requires a simple majority. There will be no strike vote.
The union opened negotiations with the company in August — a year early — as Hawker Beechcraft strives to cut costs.
A lot is riding on the outcome.
Hawker Beechcraft has received an offer from Louisiana to move its operations to Baton Rouge.
But last week the company reached an agreement with Kansas to keep the "vast majority" of jobs in Wichita contingent on a new long-term contract with the Machinists union.
Talks between the company and union broke off more than a week ago so the company and union could meet with Gov. Mark Parkinson. They resumed on Friday.
Parkinson said the state's agreement with Hawker Beechcraft would include a guarantee similar to one forged with Bombardier Learjet in July.
The state offered Bombardier Learjet $27 million in bond financing in exchange for keeping assembly of its new Learjet 85 business jet in Wichita.
In addition, Bombardier agreed not to move any existing operations out of Wichita during the life of the bonds. Learjet 85 production will support 600 jobs, including 300 new positions.
The bond financing to Learjet will be repaid from the employees' income taxes that would have otherwise gone into the state's general fund.
