A.
Each department shall be headed by a director, who shall be appointed by the Mayor with the advice and consent of the Council. Each department head shall serve during the term of office of the Mayor appointing him and until the appointment and qualification of his successor. Whenever a vacancy exists because the Mayor has not filled the directorship on an interim or permanent basis, the Mayor shall serve in that capacity until the appointment is made and approved by the Council.
B.
The Mayor may, in his discretion, remove the Administrator or any department head after notice and an opportunity to be heard. Prior to removing a department head, the Mayor shall first file written notice of his intention with the Council, and such removal shall become effective on the 20th day after the filing of such notice unless the Council shall prior thereto have adopted a resolution, by a two-thirds vote of the whole number of the Council, disapproving the removal.
