I am very concerned about labour rights, as that will be very important in a world of ever-fewer jobs with more competition for those jobs, for the students when they grow up, and for now, when their parents need jobs to support their family.
If students can get teachers fired with just an accusation,
* The students will end up with a fragmented education from a chain of supply teachers and replacements.
* Teachers will have to pander to students even more than they already do, for fear that a disgruntled student will decide to cry wolf. Lessons will focus on fun, not education, and teachers will be unable to stop students from disrupting class.
The comparison to a trader or hedge fund manager doesn't stand, as the market cannot decide to deliberately move against him out of spite, a need for power, or boredom.
[EDIT: Forgot to mention that private companies are more motivated to care about the product. Public school administrators would be more concerned about 'liability' and eliminating a source of 'hassle', than with the quality of the product. There's little incentive for them to work to keep a good teacher who's been unfairly accused.
The comparison to programmers is also not appropriate, for those same reasons.]
Others in the company can and often do. You seem unfamiliar with corporate politics.

This is why I favor holding them responsible for outcomes as well, and allowing them to be fired if things don't turn out well.
The teachers in Atlanta that were taking their students tests for them may not even end up being fired. We aren't talking about teachers not being able to be fired on a whim. We are talking about bad teachers with a history not being able to be fired.
Remember, the goal here is not to ensure teachers are never incorrectly fired, it's to educate children. If a few teachers are incorrectly fired, but student performance goes up, that's a win.
This is what happens in many industries. For example, if a trader or hedge fund manager gets unlucky and the market moves against him, he can be fired. Unfair individually, maybe, but in aggregate the net result is that the traders who aren't fired tend to perform better.
