A spokesman for federal mediators says a tentative settlement has been reached to end a strike that has shut down Boeing's commercial airplane operations since Sept. 6.
Federal Mediation and Conciliation Service spokesman John Arnold says, "We have a tentative agreement."
Francis "Frank" Larkin, a spokesman for the International Association of Machinists and Aerospace Workers in Washington, D.C., told The Associated Press the deal was reached Monday evening.
Boeing spokesman Tim Healy in Seattle said he could not immediately confirm the report.
The apparent breakthrough came on the fifth day of talks at the federal mediation headquarters in the nation's capital.
The main stumbling block in the talks had been job security.
