Boeing confirms that temporary furloughs are about to begin across the the company, including some of its defense employees here in St. Louis, as it deals with a Machinists union strike in Seattle.

Chief Executive Kelly Ortberg said the people who would be required to take time off without pay starting in the coming days include executives, managers and other employees based in the U.S.

Impacted employees will take a one-week furlough every four weeks but will still get benefits.

A spokesperson tells Spectrum News that critical customer and program work will be prioritized.

“While this is a tough decision that impacts everybody, it is in an effort to preserve our long-term future and help us navigate through this very difficult time,” Ortberg said in a company-wide message to staff.

Boeing didn’t say how many people will face rolling furloughs, but the number is expected to run into the tens of thousands. The aerospace giant had 171,000 employees at the start of the year.

About 33,000 Boeing factory workers in the Pacific Northwest began a strike Friday after rejecting a proposal to raise pay by 25% over four years. They want raises of at least 40%, the return of a traditional pension plan and other improvements in the contract offer they voted down.

The strike is halting production of several airplane models, including Boeing's best-selling plane, the 737 Max. The company gets more than half of the purchase price when new planes are delivered to buyers, so the strike will quickly hurt Boeing’s cash flow.

Ortberg said selected employees will be furloughed for one week every four weeks while retaining their benefits. The CEO and other senior executives will take pay cuts during the duration of the strike, he said, without stating how deep the cuts will be.

All work related to safety, quality, customer support and certification of new planes will continue during the furloughs, he said, including production of 787 Dreamliner jets, which are built by nonunion workers in South Carolina.

Ortberg said in a memo to employees that the company is talking to the International Association of Machinists and Aerospace Workers about a new contract agreement that could be ratified.
