Boeing will cut about 4,000 jobs in its commercial aircraft division by the middle of this year and another 550 in a division that conducts flight and lab tests.
The plane maker will reduce 1,600 positions in the commercial planes division through voluntary layoffs, while the rest of the cuts are expected to be completed by leaving open positions unfilled, spokesman Doug Alder said.
"While there is no employment reduction target, the more we can control costs as a whole the less impact there will be to employment," Alder said.
The job cuts, which will include hundreds at executive and managerial positions, will not be done through involuntary layoffs, Alder said.
Boeing will also cut about 10 percent of the approximately 5,700 jobs in its test and evaluation division, which conducts flight and lab tests, spokeswoman Sandra Angers said.
The company had a total of 161,400 employees as of December 31.
In February, Ray Conner, chief executive of Boeing's commercial aircraft business, warned employees that job cuts were necessary to "win in the market, fund our growth and operate as a healthy business."
