Plaintiff/employee suffered mental/emotional trauma but no physical injuries as the result of an armed robbery that occurred in the store while the plaintiff was on the job. Her posttraumatic stress disorder was manifest by nausea, cramps, confusion, and the side effects of her prescribed medication. She sued her employer for negligence in failing to maintain appropriate security measures in the store.

What are the arguments for and against an employer defense of workers’ compensation exclusivity with regard to plaintiff’s injuries? How should the court rule? See Rivers v. Grimsley Oil Company, Inc. [842 So.2d 975 (Fla. App. 2003)].
