William works for a large retailer. One day while at work, he slipped on a puddle of water that had accumulated on the floor in the store. The puddle had been there for several hours, and although some employees noticed it no one bothered to clean it up or use a warning cone to notify others of the leak. William suffered serious injuries because of his fall in the puddle of water. William can sue his employer for negligence under tort law
