Mary owns a medium-size distribution business with about 20 employees. Mary had an unusual management style and from time to time would throw items at her employees. Paul was working in the warehouse one hot summer day and accidentally gave a will-call customer the wrong goods. The customer came back to the office a short while later upon discovering the problem. Mary was in the office and asked who had filled his order. The customer described Paul, whereupon Mary went to the warehouse and threw a computer printout, with stock numbers and product descriptions, at Paul, yelling, "Use this, you idiot. Maybe you can do your job then!" Paul was startled, and by reflex turned to run after Mary, but slipped when he was barely under way. Paul's back was injured when the computer printout hit him, and he injured his leg when he slipped. Discuss Paul's claims.
