A chairman who is chosen by the county board may be removed, with or without cause, upon a motion adopted by an affirmative vote of four-fifths of the county board. Upon adoption of a motion to remove the chairman: (i) the chairman position becomes vacant and the former chairman's compensation shall be prorated to the date the motion was approved; (ii) the vice-chairman immediately assumes the duties of chairman without chairman compensation; and (iii) a new chairman shall be elected at the next regularly scheduled county board meeting. A chairman removed under this Section maintains his or her status as a member of the county board.
