A union-free school district is a school district in which the school employees (teachers, teachers aides, clerical employees, support staff etc.) are not represented by a labor union. This means that the wages, hours of work, and conditions of employment, including academic freedom (or the lack of it) are at the sole discretion of the employer and can be changed by the School District Administration as it deems necessary. The only limitations on this latitude are laws or regulations that may exist in State Education Codes and state or federal civil rights laws. Schools are exempt from federal wage and hour laws, so overtime in schools is not regulated.
