Boeing announced it will lay off 10% of its workforce in the coming months and cut its production amid an ongoing labor union strikes.

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.

Boeing Co. will start sending out pink slips on Wednesday to employees affected by a planned round of job cuts, a delicate balancing act between improving efficiency and keeping together a skilled workforce to help lift output again.
