All the teachers need to do is survive for the four-to-five years it takes Californians to forget what they have voted for. Then they can roll out a Proposition or local bond measure scolding voters for not funding education. Techies and other knowledge workers in particular respond very well to this kind of prodding which is why these measures pass reliably every four to five years but tend to fail if done too frequently. The unwise teachers in my town, Los Gatos, recently tried to shake down voters before the buildings promised by the previous bond measure were constructed.
The same is done with transit funding...I can't remember how many times a Measure or Proposition has passed that has promised to "finally" address transit funding...until four years pass and it is time to "finally" address it again.
