MARIETTA - Lockheed Martin's unionized workers will vote Sunday on a deal that could avert the first strike at the Marietta aircraft plant in 25 years.
Company and union officials say the apparent breakthrough came after three days of federally mediated contract talks in Georgia and California.
A Lockheed spokesman, Sam Grizzle, says the company has made its best and final offer, but he would not give details about the offer.
The International Association of Machinists says members will vote on the new proposal unday from 1 p.m. to 8 p.m. using secret ballots. The union represents 2,700 of Lockheed's 7,000 workers in Marietta.
If rank-and-file members reject the proposal, a strike could begin as planned Monday.
Lockheed builds F-22 fighters and C-130-J Hercules transports at the facility at Dobbins Air Reserve Base.
