After finally endorsing a pay deal on the table by the government and supporting its contents, AEU Tasmania branch president Helen Richardson is urging members to reject the deal after coming under fire for its relief teacher provisions.

The current deal has caused angst among the relief teacher community because it holds conditions that would mean a significant cut to their loading benefits.

The savings would be used to fund extra teachers and allow for primary school teachers to have two extra hours of planning time each week.

While that's good news for the primary school teachers, because it would bring them in line with high school teachers and allow them more breathing room, it would significantly impact on a workforce minority.

It would cut into the take home pay for relief teachers and cut into a benefit they are given because of the difficulty of the work they do.

Robbing Peter to pay Paul was never going to end well, and it's surprising the union would endorse such an offer, particularly considering they have in the past advocated on behalf of other minorities, such as teacher assistants.

A week ago, the union also released an internal poll, showing that 70 per cent of its members endorsed the current deal - the one they now say they do not support.

What the data shows is that teachers wish the negotiations to be over and its disappointing that the discussions have now taken another step backwards.

A resolution needs to be reached for all parts of the teacher workforce and discussions need to be proactive in reaching this conclusion.

Teachers and parents need this to be resolved and its hoped that this latest stumbling block will not lead to further disruption and bring employment certainty.
