The "Kid Nation" production also raised questions about whether reality show participants are more like subjects in a documentary or working actors. The latter are covered by union rules that govern everything from working hours to compensation. This debate over participant status could be seen in an American Federation of Television and Radio Artists investigation over whether its AFTRA National Code of Fair Practices for Network Television Broadcasting was violated. The investigation went forward even though on reality shows, the Network Code generally covers professional performers, but not the participants. Some parents on hand for the final day of filming accused the producers of feeding children lines, re-casting dialogue and repeating scenes, all of which suggested that the children functioned as actors. Producer Tom Forman said that the parents were observing routine "pickups" for scenes that might have been missed because of technical difficulties.
