Not trying to be mean, but why does it matter if you think it's worth it? It's my choice. If I choose a small percent chance of dying for some relief it's my choice.
I think you are unfairly describing the situation. My friend is a teacher who readily admits it would take them about two years to get fired. Two years of essentially not doing their job.
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.
