MARIETTA - Union leaders at Lockheed Martin Corp.'s massive plant in Marietta say that workers will vote Sunday on whether to strike. <br />
<br />
Union leaders have asked about 3,800 employees represented by Local 709 of the International Association of Machinists to reject what the company termed its last and best proposal for a new three-year contract. <br />
<br />
The current contract expires at 12:01 a.m. Monday. Members are scheduled to take a strike vote Sunday between noon and 8 p.m., with results expected by 10 p.m. <br />
<br />
Local 709 represents factory, technical and office workers including mechanics, electronics technicians and assemblers at the Marietta plant, which has nearly 8,000 employees. <br />
<br />
Workers at the plant, just north of Atlanta, struck over contracts in 2002 and 2005 but voted to ratify a three-year deal in March 2008, ending a strike threat that year. <br />
<br />
The Bethesda, Md.-based firm manufactures fighter jets and other military hardware. <br />
