The company, however, plans to suspend production this month as the grounding, which cost former CEO Dennis Muilenburg his job just before Christmas, wears on longer than the company had signaled. On Monday, Boeing told employees that it would need to temporarily reassign some 737 Max workers to other aircraft or storage facilities for the planes as it prepares to shut down production this month. Meanwhile, Spirit Aerosystems, which makes fuselages for the planes, said Monday that it's considering voluntary layoffs for some employees to cut costs, as the grounding continues.
