Strike action is on the table - if the public servants' union can't come to an agreement with Government over pay.

The union's meeting with Prime Minister Jacinda Ardern tomorrow to discuss the public sector wage freeze.

Finance Minister Grant Robertson is rebutting claims it's a freeze, saying teachers, nurses and police officers will continue to be able to cross into higher pay bands.

But PSA  national secretary Kerry Davies told Heather du Plessis-Allan thousands of public servants don't have pay bands.

She hopes the Government will listen to their concerns.

“If not, then yes we will be going into collective bargaining with opposing positions, which does not make for very good bargaining outcome.”
