Aircraft structures supplier Spirit AeroSystems issued lay-off notices to 150 more salaried workers and managers on 12 September, increasing overall staff reductions to 410 since late-July.
The latest round of lay-offs, which were previously announced, are focused on the company's professionals and managers in Wichita, Kansas. The initial round of lay-offs targeted another 360 salaried workers and managers working in Oklahoma.
A "significant", but undisclosed, number of additional employees have also volunteered to retire or be made redundant with lump-sum severance packages.
Spirit AeroSystems has been internally restructuring its costs since reporting more than $1 billion in write-offs over the last 18 months, primarily as a result of cost overruns while developing new wings for aircraft including the Boeing 787.
At the same time, Spirit AeroSystems is increasing hiring of hourly factory workers by several hundreds. The manufacturing employees are needed to meet rising demand for commercial aircraft structures, as Airbus and Boeing are both at record production rates.
