Last in First Out (LIFO) (or otherwise known as "Last One Hired is the First One Fired" is a policy often used by school districts and other employers to prioritize layoffs by seniority. Under LIFO layoff rules, junior teachers and other employees lose their jobs before senior ones. Laying off junior employees first is not exclusive to the education sector or to the United States, but is perhaps most controversial there. LIFO's proponents claim that it protects teachers with tenure and gives them job stability, and that it is an easily administered way of accomplishing layoffs following a budget cut. LIFO's critics respond that it is bad for students. They prefer that the best teachers remain regardless of how long they have been teaching.
