Elementary school Assistant Principal Kourtney Glaser began bleeding heavily during a school district training session. She was taken to an emergency room, where doctors determined her IUD had lodged in her uterine wall. She's OK now and wants to get back to work. But officials with Michigan's Eagle Mountain-Saginaw School District are refusing to allow her to come back. They say her problems were caused by anxiety and are demanding notes from two doctors and the release of her medical records before they will let her return.
