Mrs. Ek, while working at See’s, caught COVID allegedly due to See’s negligent failure to implement procedures to prevent spread of infection.  While Mrs. Ek was home sick, she infected Mr. Ek, who later died of COVID.  This decision holds that the Workers Comp. Act does not preempt Mr. Ek’s heirs’ wrongful death suit.  The derivative injury doctrine under which tort claims for relatives’ emotional distress and other derivative injuries are preempted along with claims for the worker’s own injury does not apply where there is only a causal link between the worker’s injury and the relative’s injury.  Thus, here the fact that the employer’s negligence allegedly caused Mrs. Ek’s infection which in turn caused Mr. Ek’s infection and later death is insufficient to invoke the derivative injury doctrine and Workers Comp. preemption.
