If they do... they're stupid and probably become administrators within the first 5 years. ( It occurs to them: "Like, uhh, this is HARD."
Most teachers like kids, like the relative autonomy that teachers ( used to) have, the chance to develop intellectual interests that would be denied them in a typical corporate office and ... at least in a lot of cases .... like the fact that their work schedule follows the school calendar.
So... you're right, the idiotic merit pay schemes floated by these corporate "reform" geniuses ( who are completely convinced that everybody n the world thinks EXACTLY the way THEY do) are dead in the water; completely lost on teachers.
I think you have teachers clamoring for better schools for kids because that IS in their own material self interest as well. It sounds self serving because it IS self serving. But in fact, the interests of both consumer and provider tend to be aligned on many issues in education ( not by any means ALL) and pretty much ALL of the biggies: safe schools, good funding, classrooms and curricula that *work*, limited bureaucracy, and administrators who understand teaching and learning. These things help EVERYONE.
We haven't had a raise in NYC since.... I think.... 2009, and are not going to get one soon. But that's far from what teachers here are worried about these days. They're worried about being fired over nonsense, having no real union, and being worked to exhaustion ( i.e. burnout) by "reform"-generated paperwork and statistic-gathering.
