SpaceX has been sued again over the mass firing of at least 200 workers in July. A second class action suit has been filed alleging a violation of California’s Worker Adjustment and Retraining Notification (WARN) Act, which requires 60-days notice of the firing of 50 or more workers, according to Law360.com

Space Exploration Technologies Corp. was hit with another proposed class action in California state court on Tuesday over the aerospace company’s alleged failure to give workers notice of a mass layoff in July, marking at least the second suit over the firings.

A class action lawsuit filed earlier in August made the same allegation. SpaceX claims WARN doesn’t apply because the workers were not laid off but were let go for cause after the company finished its annual performance reviews.

SpaceX faces two other lawsuits filed in August. One claims the company broke the law by failing to provide regular rest and meal breaks. The other alleges racial discrimination in employment and promotions.

SpaceX has denied all these allegations and said it will vigorously defend itself in court.
