Production employees at the former Vought Aircraft plant in North Charleston will vote next month on whether to decertify the election that made them part of the International Association of Machinists and Aerospace Workers, the union said Tuesday.

The Sept. 10 vote be overseen by the National Labor Relations Board, said IAM spokesmen Bob Wood.

"We're going to work hard to educate and inform our members — everybody out at the plant — about what this means," he said. Wood said if the decertification effort succeeds, it would be "very difficult" for the workers to reorganize if they so chose in the future.

The Vought plant was recently sold to Boeing Co. in a deal valued at $1 billion. The factory supplies fuselage section for Boeing's 787 passenger jet.

Boeing has said it would recognize the union and negotiate a new labor contract covering the local IAM workers if the election decertification fails.

Boeing has had strained relations with the IAM over the years, raising concerns in its longtime manufacturing base near Seattle that the company might build a second 787 assembly line in North Charleston. If the local union members choose to disband, that could be viewed as an advantage for South Carolina.

A worker at the former Vought factory requested to decertify the election last month. The vote will be held at the plant off International Boulevard.
