In a county which has adopted any form of county managership, neither the board of county commissioners nor any of its committees or members shall direct or request the appointment or removal of any person by the county manager or any of the manager’s subordinates nor in any manner take part in the appointment or removal of officers or employees in the administrative service of the county. Except for the purpose of inquiry or in an emergency, the board of county commissioners and its members shall deal with that portion of the administrative service over which the county manager is responsible solely through the manager. Neither the board of county commissioners nor its members shall give orders to any subordinate of the county, either publicly or privately. Any member of the board of county commissioners who violates any provision of this section shall be guilty of a class A misdemeanor and, in addition to the penalty prescribed for such an offense, shall forfeit the person’s office.
