Be sure to dress and behave professionally at all times. Although hearings are naturally adversarial, do your best to remain calm and polite when speaking to witnesses, your employer, and the judge. Judges are concerned with the facts of the case, so do not view the hearing as an opportunity to seek revenge or insult your former employer by being rude or argumentative. Simply use your knowledge of the situation and any evidence you have to show that your version is supported by the facts.
