In Kaiser Co. v. Ind. Acc. Com. (Pruitt) (1944) 65 Cal. App. 2d 218, the court held that an employee sustained a compensable injury when she tried to intervene in a fracas that arose when a male employee was confronting several female employees whom he believed had told his wife he was having an affair with another female employee. The court stated: "'This view recognizes that work places men under strains and fatigue from human and mechanical impacts, creating frictions which explode in myriads of ways, only some of which are immediately relevant to their tasks. Personal animosities are created by working together on the assembly line or in traffic. Others initiated outside the job are magnified to the breaking point by its compelled contacts. No worker is immune to these pressures and impacts upon temperament. They accumulate and explode over incidents trivial and important, personal and official. But the explosion point is merely the culmination of the antecedent pressures. That it is not relevant to the immediate task, involves a lapse from duty, or contains an element of volition or illegality does not disconnect it from them nor nullify their causal effect in producing its injurious consequences. Any other view would reintroduce the conceptions of contributory fault, action in the line of duty, nonaccidental character of voluntary conduct, and independent, intervening cause as applied in tort law, which it was the purpose of the statute to discard. It would require the application of different basic tests of liability for injuries caused by volitional conduct of the claimant and those resulting from negligent action, mechanical causes and the volitional activities of others.'"
