Lockheed Martin, Machinists Reach Tentative Pact: Details of the proposed labor contract between Lockheed Martin Corp. and Machinists Union leaders won’t be made public until they are released to the 12,500 rank-and-file members at three plants in the next two days. The Lockheed Martin plants are in Marietta, Ga.; Palmdale; and Sunnyvale, Calif. Union members at all sites will vote on the three-year pact Wednesday, the union said. The proposal reportedly provides members with wage increases, improved cost-of-living benefits and higher pension and savings plan benefits. The union’s negotiating committee is unanimously urging members to approve the accord. Bethesda, Md.-based Lockheed Martin could not be reached for comment.
