Felix Santos, Carlos Garcia, and Jose A. Valdes Prieto were stock persons for Cuba Tropical, Inc., a supermarket supplier. They regularly worked over 40 hours per week, but they were not paid overtime. They brought suit to recover their overtime pay against Cuba Tropical as well as Jose L. Rodriguez, a co-owner of Cuba Tropical. Mr. Rodriguez has no control over the hiring and firing of employers, does not establish their working hours, and did not visit the warehouse where the three employees worked. He hired managers for the business and had them handle the day-to-day operations. He was required to sign certain documents for the corporation, but he did not sign any checks personally. Can Mr. Rodriguez be held personally liable for the overtime wages that are due to the three men?
