All superintendents of departments and officers are the agents of the City Council only, and all their acts shall be subject to review and to approval or revocation by the Council. Every superintendent or officer shall, from time to time, as required by law or ordinance, or whenever he shall deem necessary for the good of the public service, report to the Council in writing respecting the business of his department or office on matters connected therewith. The Council may, by ordinance or resolution, assign to a superintendent, officer or employee, duties in respect to the business of any other department, office or employment, and such service shall be rendered without additional compensation.
