279.43  Reporting inappropriate teaching assignments.
  An employee licensed by the board of educational examiners and holding a contract as described in section 279.13 shall disclose any occurrence of a teaching assignment for which that employee is not properly licensed to the school official responsible for determining teaching assignments. Failure of the employee to disclose this occurrence or failure of the school official responsible for determining teaching assignments to make appropriate adjustments to the employee’s teaching assignment once the employee discloses the occurrence shall constitute an incident of misconduct as provided in section 256.146, subsection 13, and is actionable by the board. If the school official fails to make appropriate adjustments to the teaching assignment once disclosure by the employee is made, the employee shall report this occurrence to the department or to the board for further action.
