EVERETT — The Boeing Co. issued 580 layoff notices in April, according to state records.
Most went to union workers: 217 to members of the International Association of Machinists and Aerospace Workers and 277 to members of Society of Professional Engineering Employees in Aerospace. Some of those people already had been laid off, and received new notices with revised last day of employment.
It is not clear how many non-union workers were laid off or received notices with new end dates.
Boeing has slashed its workforce in recent years, mostly through buyouts and attrition. The aerospace giant had 70,640 workers in Washington and 146,962 worldwide at the end of March, the most recent data available.
Company executives have indicated more layoffs could come later this year.
