Before implementing a flexible learning year program in any facility of the district, the board must negotiate with the teachers, principals, assistant principals, supervisory personnel and employees to the extent required by the Public Employment Labor Relations Act, and must consult with the parents of pupils who would be affected by the change, and with the community at large. These procedures must include at least three informational meetings for which the board has given published notice to the teachers and employees and to the parents of pupils affected.
