According to the Charter if the Mayor is absent the city Council Chair would be the Mayor this is what the charter says,
Section 5.4. Mayor Pro Tem.
In case of the absence or disability of the Mayor, the Chairman of the Council shall perform the duties of the Mayor during the period of such absence or disability; provided however, that he shall not have the power of veto, and shall not have the power to remove the director or head of any department during any period in which he shall act in the capacity of Mayor unless he has so acted for a period of thirty (30) consecutive days; any appointment made by the Mayor Pro Tem in accordance with these provisions shall not be permanent until such appointees shall have served for a period of sixty (60) days following his appointment.
Who do you think the Mayor considers Mayor Pro Tem? His assistant, the Mayor when asked during his deposition who he considers to be the Mayor in his absents? He said Krystina Kramarz in clear violation of the charter, but who’s paying attention to such an insignificant document as the charter? This administration has turned the charter in to nothing more than a bunch of words that have little or no power when applied to them..
