Mario Echazabal V. Chevron US
Beginning in 1972, Mario Echazabal worked for freelance contractors at a refinery owned by Chevron U.S.A. Inc. once Echazabal applied for employment directly with Chevron, the company's physical examination discovered he had a liver condition, the cause known as hepatitis C. Chevron's doctors concluded that the condition would be exacerbated by more exposure to toxins at the industrial plant. In response to Chevron's request that the industrial plant transfer Echazabal to employment without exposure to toxins or fire him, the contractor employing him laid him off. Echazabal filed suit, claiming that Chevron's action violated the Americans with Disabilities Act of 1990 (ADA). under an Equal Employment opportunity Commission (EEOC) regulation
