Union workers voted Sunday on whether or not to go on strike in opposition to a three-year contract proposed by Lockheed Martin.
Company and union negotiators failed to reach tentative agreements in three separate sets of contract negotiations that concluded March 3rd.
The proposed agreements would cover the nearly 6,000 International Association of Machinists represented employees at Marietta, Ga.; Palmdale and Sunnyvale, Calif.; and several field locations.
Leaders of Local 709 in Marietta Georgia have asked their members to reject the final contract proposal and urged the 3,500 employees it represents to vote to strike.
Union members will hold two votes Sunday.
The first vote is to accept or reject the proposed contract; approval requires a simple majority vote.
They will then take a second vote Sunday on whether to go on strike when the current contract expires.
That vote requires a two-thirds majority.
