Inability to work full-time due to school merger requires subject continuity unless student welfare or staffing needs dictate otherwise.

The Supreme Court dismissed the teacher's cassation appeal against her transfer to inactive status following a school merger. The lower court found that while the merger reduced her teaching hours, the school reasonably assigned her to a different subject because she lacked qualifications for the new role and had higher credentials than available librarians. The court ruled that the statutory provision regarding full-time work impossibility applies to the teacher's current subject unless changes are driven by student welfare or staffing gaps.
