Boeing said it will meet Friday with Machinists representatives in St. Louis under the auspices of federal mediators, after the union warned it could strike as soon as next week.

ST. LOUIS — Boeing said it will meet Friday with Machinists representatives in St. Louis under the auspices of federal mediators.

The company agreed to a request from the Federal Mediation and Conciliation Service after the union said it planned to notify Boeing that it could strike in as little as a week.

The Machinists postponed delivery of the strike notification, Bloomberg News reported.

The workers voted down Boeing’s last offer on Sunday. The notice says they could strike as soon as June 23.

The International Association of Machinists and Aerospace Workers represents about 2,500 Boeing workers in St. Louis.

The union says Boeing has not made any attempt to schedule negotiations after workers rejected the company offer.

“We certainly want to take every effort to avert a work stoppage and we view this as an opportunity to clarify our best-and-final offer,” the company said in a statement..
