In assigning, reassigning, or transferring a teacher, whether voluntary or involuntary on the part of the teacher, the superintendent shall not use seniority or continuing contract status as the primary factor in determining the teacher's assignment.

(B) Notwithstanding any provision to the contrary in section 4117.10 of the Revised Code, the requirements of this section prevail over any conflicting provisions of agreements between employee organizations and public employers entered into on or after the effective date of this section.
