The Public Service Association says the Government needs to stop coming after doctors' right to strike, and get back to the bargaining table

Tens of thousands of union members across health, education, and the public sector are downing tools on Thursday.

Health Minister Simeon Brown was booed at a doctors' union conference yesterday, where he told them strikes were unethical.

He told RNZ a law change may have to be considered if strike action continues.

PSA National Secretary Fleur Fitzsimons says the Government should be listening to these workers.

She says they need to shift away from this constant rhetoric, that undermines doctors concerns.
