The duties assigned to administrative officers shall be exercised under the supervision of the Manager. In all cases required by ordinance or in which the manager may deem it advisable, the City Manager shall take of any person appointed a bond, payable to the City of Wheeling conditioned on the faithful performance of the person's duties, and in such amount as the City Manager shall deem requisite. Such bonds shall be filed with the City Clerk. No person shall be appointed in the executive or administrative services of the City who has been convicted of bribery, perjury, felony or other infamous crime. But residence within the City at the time of such appointment shall not be a necessary qualification for appointment unless the Constitution of the State shall provide otherwise. If the City Manager or any other officer of the City shall be a member, manager, officer or stockholder of any partnership, business, firm or corporation, which by contract furnishes material and supplies to the City or to any workman or contractor for the City, that shall not of itself constitute a disqualification for office under this Charter. Unless otherwise provided by this Charter or by ordinance, the City Manager shall fix the compensation for all persons in the executive and administrative services of the City, within the limits and terms of the budget.
