The document summarizes the process for filling teacher vacancies in Minneapolis Public Schools as defined in the teachers' union contract. There are four types of teachers who can fill vacancies - voluntary transfers, excessed, unassigned, and new hires. The process involves posting vacancies, interviews, and seniority-based bidding where the teacher with the most seniority who bids gets the job. Reducing or eliminating teaching positions is also determined by seniority, with less senior teachers losing positions first.
