The City Council may contract with temporary help firms for temporary help to assist city agencies, departments or offices during any peak load, temporary absence, or emergency, provided the Council determines that it is in the economic interest of the city to provide such temporary help by contract, rather than employing persons for such purposes. Use of temporary help under this section shall be limited to a period of not to exceed ninety (90) days for any single peak load, temporary absence, or emergency situation. Temporary help furnished by temporary help firms pursuant to contract as authorized by this section shall not be deemed to be officers or employees of the city and Article VIII of this Charter shall have no application to such temporary help.
