A quick Google search will show this stands for Worker Adjustment and Retraining Notification (WARN) Notice where companies with over 100 employees have to file with the state to give employees 60 days notice. It varies by state but wasn't sure if 7E violated any rules there?
Also if you google WARN Above they have a publicly viewable file that shows companies that have files and WILL be doing layoffs soon. It's just sitting there
