Section 85.23 of the Iowa Code requires that the injured worker report an injury within ninety days of the injury (not whatever time limit the employer will try to set). Section 85.24 says that the noitice only tell an agent of the employer that a work injury happened on or about a certain date, along with the nature of the injury.

someone on the dependent's behalf shall give notice thereof to the

employer within ninety days from the date of the occurrence of the

injury, no compensation shall be allowed."
