This site keeps a register of job cuts linked to AI: a cut enters it when the employer names AI or automation as a reason, or when a credible outlet or a named analyst links it to AI, and each entry is graded on what the employer itself said. Mosaic's cuts were read against that rule and left out. They are shown here because people searching for Mosaic's layoffs ask whether AI was behind them, and are counted nowhere on this site. How the register decides.
Yes: Mosaic filed 2 WARN notices for 405 jobs in Florida and Louisiana since January 2025. The latest was published Oct 14, 2026 in Florida, for 199 jobs.
A WARN notice is the advance warning a US employer must file with a state before a mass layoff or a site closure, usually 60 days ahead. It names the site and the number of jobs but gives no reason, so on its own it says nothing about AI.
