Boeing has delivered layoff notices to more than 400 members of its professional aerospace labor union, part of thousands of cuts planned as the company struggles to recover from financial and regulatory trouble as well as an eight-week strike by its machinists' union.

The layoff notices were issued last week to members of the Society of Professional Engineering Employees in Aerospace (SPEEA), with affected workers remaining on the payroll until mid-January.

WASHINGTON, Nov 13 (Reuters) - Boeing said on Wednesday it is issuing layoff notices starting this week to workers impacted by a broader plan by the heavily indebted planemaker to cut 17,000 jobs, or 10% of its global workforce.
