Plaintiff was injured while working for a sign company when a ladder slipped on an allegedly slippery floor. The parties agree that the plaintiff was a business invitee; however, the trial court granted defendant’s motion for summary judgment concluding that plaintiff had not presented any evidence from which a jury could find that the defendant had breached a duty to plaintiff.

It appears that the trial court failed to understand that the burden on motion for summary judgment was on the defendant to conclusively prove no genuine issue of material fact as to whether this floor was slippery, Dade County Sch. Bd. v. Radio Station WQBA, 731 So.2d 638 (Fla. 1999), and in this case the defendant did not sustain that burden. Although a jury could well find that plaintiff, who was placing an extension ladder on the floor and against the side of a wall, had as much knowledge of the slippery condition of the floor as the defendant, that merely raises the issue of comparative negligence. Fenster v. Publix Supermarkets, Inc., 785 So.2d 737 (Fla. 4th DCA 2001). Reversed.
