Boeing has issued layoff notices to 438 members of the Society of Professional Engineering Employees in Aerospace (SPEEA) this week as part of a broader effort to reduce its global workforce by 10%, according to KIRO Newsradio.

Boeing has laid off more than 400 members of its professional aerospace labor union, part of company-wide cuts that will reach 10% of Boeing's workforce.

Boeing started issuing layoff notices Wednesday to 17,000 employees to cut 10% of its workforce in an effort to shore up the aerospace giant's shaky finances.
