From an Associated Press story from Chicago:

Clarence Notree barely had time to act when a gunman burst into the elementary-school gym. As the bullets flew, the physical-education teacher spread out his arms to shield the children and pushed them out a door to safety. He got shot in the wrist. His school and community lauded Notree as a hero, but the Chicago Board of Education insisted that he wasn't entitled to worker's compensation. They said saving the children's lives was not part of his job.
