209. (1) The persons holding pedagogical or educational positions who are contemplated in section 208 and who have not received the notification mentioned therein or who have not been reengaged in accordance with the provisions of the collective agreement shall remain engaged for the following year upon the same terms, unless one of the causes specified in section 190 or in the collective agreement may be invoked against them. They shall remain engaged under the same conditions of employment if they continue to hold the same pedagogical or educational positions; they shall not be so engaged under other conditions unless they are assigned to another pedagogical or educational position and have been notified of such change of assignment and conditions in accordance with the provisions of the collective agreement or, failing such agreement or if it does not provide therefor, of the individual contract governing such persons.
(2) Except in the cases provided for in sections 190 and 208 and in subsection 1 of this section, no school commissioners or trustees need employ a person whom they deem unsuitable to hold a pedagogical or educational position.
