US layoff data from 1988 to present
WARNtracker.com scrapes publicly available information about company layoffs from WARN notices. A WARN (Worker Adjustment and Retraining Notification) notice is a notice required by the federal WARN Act in the United States, which mandates that employers with 100 or more employees provide at least 60 days advance written notice of a plant closing or mass layoff affecting 50 or more employees.

WARNtracker.com is managed by two long-time software engineers who wanted to help their friends understand the broader layoff environment. The database has been built using publicly-available information that employers are required to file with certain states when they perform large layoffs. They create WARN data from a combination of requesting records from state government agencies directly, news sources, and double checking with various layoff trackers.
