I work to my contract. If you don't like the contract, get a new contract during negotiations - the same way any other company would have to deal with it.

I'm begging you to stop making a fool out of yourself, though. No teacher is so vindictive. You want quality educators? Pay them. Simple as that. Far better to strike for a lousy one week than watch a slow leak of qualified veterans turn to other fields. Even lower-paying fields that are just easier to process and handle healthily.
