Federally mediated negotiations to end a 52-day strike against the Boeing Co. resumed Monday for a fifth day after running into the wee hours the night before.
Talks at the Federal Mediation and Conciliation Service in Washington, D.C., on Sunday went past midnight, said Connie Kelliher, a spokeswoman for the International Association of Machinists and Aerospace Workers in Seattle.
Kelliher and Tim Healy, a Boeing spokesman, confirmed that the negotiations resumed Monday after a break so the participants could get some sleep.
Mediators called the two sides to the table Thursday under a news blackout, and neither Boeing nor union officials have said whether there has been any progress.
Key issues include job security, wages, retirement benefits and medical coverage.
The strike has shut down Boeing's commercial aircraft operations since Sept. 6, three days after Boeing's last offer was rejected with an 87 percent strike vote. Two days of last-ditch talks to avoid a strike failed, and another two-day round of negotiations collapsed Oct. 13. Mediators were involved in both of those efforts.
