Either a teacher or a school district can breach a contract. Whether a breach has occurred depends on the facts of the case and the terms of the contract. Breach of contract cases between teachers and school districts arise because a school district has terminated the employment of a teacher, even though the teacher has not violated any of the terms of the employment agreement. In several of these cases, a teacher has taken a leave of absence, which did not violate the employment agreement, and the school district terminated the teacher due to the leave of absence. Similarly, a teacher may breach a contract by resigning from the district before the end of the contract term (usually the end of the school year).
