The county commissioners have final authority over the operation of all county offices by elected or appointed county officials, except in circumstances for which a County Personnel Board has been established under subchapter VII, article 2 with the powers and duties set forth in that article and in section 501. The county commissioners must act as a board and not on an individual basis in exercising this authority.   [PL 1989, c. 6 (AMD); PL 1989, c. 9, §2 (AMD); PL 1989, c. 104, Pt.
