As a safety measure, Dynea USA, Inc., required an employee, Tony Fairbanks, to wear steel-toed boots. One of the boots caused a sore on Fairbanks's leg. The skin over the sore broke, and within a week, Fairbanks was hospitalized with a methicillin-resistant staphylococcus aureus (MRSA) infection. He filed a workers' compensation claim. Dynea argued that the MRSA bacteria that caused the infection had been on Fairbanks's skin before he came to work. What are the requirements to recover workers' compensation benefits? Does this claim qualify? Explain.
