Microsoft Layoff History

Microsoft has filed 20 official WARN Act notices with state labor departments, spanning 2004 through 2025. These notices cover approximately 11,302 employees across Washington.

Layoffs at major employers like Microsoft are often driven by restructuring after mergers or acquisitions, cost-cutting in response to changing market conditions, the consolidation of overlapping roles following integrations, or broader industry downturns. The WARN Act filings listed here represent only the legally required public notices — actual workforce reductions may be larger.

The Worker Adjustment and Retraining Notification (WARN) Act requires employers with 100 or more workers to provide 60 days' advance written notice before a mass layoff or plant closing. Failure to do so entitles affected employees to up to 60 days of back pay and benefits. WARN filings are public record — LayoffCentral.com aggregates them directly from state labor department databases.

Microsoft's most recent WARN Act filing was recorded on 2025-11-07. WARN data often surfaces layoffs before press releases or news coverage, making it one of the earliest signals of corporate workforce reductions.
