What this means for WA workers
Microsoft has 16 recorded WARN filings covering 20,156 workers, most recently on Sep 8, 2025.
WARN Act filings only capture layoffs of 50+ workers at sites of 100+ employees, so smaller reductions, contractor non-renewals, and voluntary separations are not shown here.
With 16 separate WARN Act filings in this dataset, Microsoft has one of the more extensive recorded layoff-notice histories, covering 20,156 workers from Jul 17, 2014 through Sep 8, 2025, and even that likely understates the real total (why). By total workers affected, Microsoft ranks #3 of 757 tracked employers in WA. Among the 8 other Information Technology employers with recorded WARN filings, the median is 2,550 affected workers -- Microsoft's 20,156 sits well above that group's typical scale. Every recorded filing was reported to WA's workforce agency, in the Information Technology sector -- a single-state footprint, unlike the multi-state pattern common among larger employers.
Averaging 1,260 workers per notice, Microsoft's filings fall into a pattern that resembles full-facility closures or company-wide restructuring, events that can reshape local labor markets for years. With 16 separate recorded filings, this is not an isolated event, the cadence of notices points to recurring workforce adjustment tied to industry cycles, merger integration, or capacity right-sizing.
Workers on WA-based Microsoft notices should contact the WA workforce agency directly, response teams, severance negotiation guidance, and TAA (Trade Adjustment Assistance) screening move fastest in the days immediately following a notice.

This record reflects filed notices only; subsequent hiring, rescinded closures, or facility reopenings are not tracked by WARN disclosures.

The Worker Adjustment and Retraining Notification (WARN) Act requires employers with 100+ employees to provide 60 days advance notice of plant closings and mass layoffs affecting 50 or more workers. Not all layoffs require WARN notice.
Workers affected by a WARN-notified layoff may be eligible for unemployment insurance, COBRA health coverage continuation, job retraining through the Trade Adjustment Assistance program, and severance packages if offered by the employer. State workforce agencies often provide additional rapid response services.
Microsoft has affected 20,156 workers across 16 WARN filings in the Information Technology sector. The federal WARN Act only captures layoffs affecting 50 or more workers, so actual workforce changes may be larger.
