I believe it was called off by the teachers as a good faith gesture to get the government back to the negotiating table. Next week's strikes remained in place to encourage a better offer, which hasn't happened.
Can you find a source for the union demanding a 30% pay rise?

I don't think you can!

Still no proof of your claim. Some could mean 2 or some could mean 200.
Please show me where it says less than 200 teachers voted to strike.

The burden of proof is always on the person making an assertion or proposition. Shifting the burden of proof, a special case argumentum ad ignorantium, is the fallacy of putting the burden of proof on the person who denies or questions the assertion being made.
