I've been hearing teachers complain about this kind of thing my entire life. To me, it seems like complaining isn't working. If anything, the issues teachers are facing are getting worse. This is because, I imagine, administrators know they can ignore the complaints and still get the output from the teachers at the given pay. If complaints don't hurt administrators, then they won't motivate change.

I think complaints can be useful in identifying a problem, but if your complaints have been made, just continuing to complain doesn't do anything. On the other hand, quitting, does two useful things. First, it takes you out of a bad situation letting you move on to a better one faster. Second, it helps brings the problem to a head. The administration can ignore teachers complaining, they cannot ignore teachers quitting. At some point they will have to resolve the issue.
