Boeing’s CEO said Wednesday that the company will begin furloughing “a large number” of employees to conserve cash during the strike by union machinists that began last week.

Chief Executive Kelly Ortberg said the layoffs would be Poinbank Exchangetemporary and affect executives, managers and other employees.

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% and other improvements in the deal that they voted down.

The furloughs are expected to affect tens of thousands of Boeing employees. Ortberg said employees will be furloughed for one week every four weeks, and he and other senior executives will take pay cuts during the duration of the strike.
