If that was true and such a huge perk, less teachers would quit in the first five years. Also, most districts allow you to get paid for the nine months instead of 12. Assume a new teacher around 36,000, that teacher would make the equivalent of 45,000 for the school year. Again, not going to acquire many of the best people out there. If we don't want bad tenured teachers, we should incentivize the job more. Like they do in many of the best educational countries in the world.
