The Board expects the superintendent to devote his or her undiminished attention and energy to the concerns of the school district. He or she may not be engaged in any other employment nor in long-term consulting assignments. However, the Board recognizes the superintendent's obligation to contribute to the profession of school administration and to the cause of public education generally. This policy, therefore, does not prohibit the superintendent from undertaking occasional consultative work which does not conflict with obligations to the system. Any such task that requires the superintendent's absence for three or more days must have prior approval of the Board.
