1.Be at the top of the salary scale.
2.Be close to vesting in lifetime benefits.
3.Be an advocate for your students and their families.
4.Make sure that the principal dislikes you. It can be because you are popular with the staff or parents and he or she is not. It can be because you have spoken up in meetings opposed to a proposal of the district or the principal. It can be just because.
