In an ongoing effort to trim its workforce, Microsoft said as much as 4%, or roughly 9,000, of the company’s employees could be affected by Wednesday’s layoffs. In Washington, 830 employees were let go, according to a regulatory filing Wednesday.

Microsoft says it is laying off about 9,000 workers, its second mass layoff in months and its largest in more than two years.

The tech giant intends to reduce organizational layers by having fewer managers and streamlining its products, procedures and roles, Microsoft said Wednesday.
