The union meeting was the second of four scheduled in Whanganui, as meetings are being called nationwide.
"It was very positive, the teachers are right behind the whole thing," Mr Whitworth said.
He predicts that over the next two meetings a further 130 primary school teachers will get the chance to listen and have their say.
"The mood was very strong today, they're very supportive of our proposed claims, we had one hundred per cent endorsement from this particular meeting," he said.
"Now, we move on to the next meetings and then nationally we will get the feedback to see if the negotiating team can take it over to the negotiating table."
The issues will be discussed again at next week's meeting at Whanganui Intermediate School on Tuesday, March 27.
