Plaintiff’s complaint alleged a viable claim for employer liability outside the Workers Compensation Act for a worker’s injury due to the employer’s fraudulent concealment. Lab. Code 3602(b)(2). Three elements comprise a fraudulent concealment claim: “(1) the employer knew that the plaintiff had suffered a work-related injury; (2) the employer concealed that knowledge from the plaintiff; and (3) the injury was aggravated as a result of such concealment.” Here, the complaint alleged that defendant knew plaintiff’s decedent had contracted COVID-19 on the job because defendant housed the workers in close quarters in a hotel and knew both that there had been a COVID-19 outbreak at the hotel and that the decedent reported symptoms consistent with a COVID-19 infection. The complaint alleged that defendant didn’t tell the decedent he had COVID-19 or that there was an outbreak of the disease. And the delay in treating decedent for COVID due to the employer’s concealment aggravated the disease causing the worker’s death.
