For the purpose of safety and protection, GE Healthcare, Inc., required their operations employees, including Jennifer Willis, to wear steel-toed boots. One of Willis’s boots caused a sore on one of Willis’s legs. The skin over the sore broke, and within a week, Willis was hospitalized with a methicillin-resistant staphylococcus aureus (MRSA) infection. She filed a worker’s compensation claim. GE Healthcare, Inc. argued the MRSA bacteria that caused the infection had been on Willis’s skin before she came to work. Based on the rules that cover workers’ compensation claims, how will the courts rule regarding Willis’s claim of a workplace injury?
