Bader v. Northern Line Layers, Inc., 503 F.3d 813 (9th Cir. 2007)

The Worker Adjustment and Retraining Notification Act (“WARN”) requires employers to give employees at least 60 days’ notice in the event of a plant closing or mass layoff at a “single site of employment.” The issue in this case was whether the site of employment of the construction worker-plaintiffs was the company’s headquarters or the workers’ actual work sites. The Ninth Circuit affirmed summary judgment for the employer after concluding that the plaintiffs had failed to raise a genuine issue of material fact whether 50 or more people were laid off at a single site of employment. The Court concluded the remote construction locations where plaintiffs worked did not qualify as a single site of employment under the applicable regulations.
