Anti-Fraud Unit. The Department of Industrial Relations (DIR) takes fraud seriously. DIR works to identify, combat and prevent fraud that affects California’s 18 million workers. Fraud costs taxpayers billions and hurts law-abiding employers as well. When employers misclassify or understate workers, report inaccurate payroll, do not report work injuries or encourage workers to submit fraudulent workers compensation claims—this is fraud. Fraud also occurs when unscrupulous medical providers abuse injured workers in the workers compensation system. Help protect the integrity of our programs and report fraud when you see it.



Cal/OSHA protects workers and the public from safety hazards and provides consultative services to employers.
