Adam is an employee of a grocery store. He stocks shelves. One afternoon as he was restocking the shelves in the condiment aisle, a patron of the store, careened into him with his grocery cart, knocking Adam to the floor and with him several items from the shelves. Adam, upset, reacted by shoving the patron who slipped and fell on some mustard, and broke his leg on impact with the floor. Is this an intentional tort Adam carried out? If so, which one? Will Adam's employer be vicariously liable if criminal charges are laid against Adam?
