In education, this is not the end. The stakes are not about money. The product of my work is not money, but about the development and fostering of the next generation of citizens of this country. The justification of employment is not so black and white as "Does Employee X make money for the company?" A teacher should be judged as to whether they truly are developing and fostering and properly educating the next generation of citizens of this country. However, the actual evaluation is very difficult to accomplish and it is nearly impossible to monetarily evaluate the effectiveness of an educator. Budget crunches, personality differences, wearing the wrong colored tie, looking at someone funny, one rogue parent, and a student who doesn't like a grade, would all be common causes for dismissal for teachers if there were not unions.
