There could be some interruption to government services next week, as one of the biggest federal departments takes strike action.

Centrelink, Medicare and Child Support workers at the Department of Human Services (DHS) will strike on six days between February 15 and February 24.

Staff are attempting to break a 3-year impasse on their pay negotiations, and more recent disputes caused by Centrelink's controversial “robo-debt” recovery policy.

“This action has the potential to impact Centrelink, Medicare and Child Support services across Australia,” DHS spokesperson Hank Jongen said.

“If there are disruptions they will be to our telephone and face to face services on Monday, Wednesday and Friday.

“We're asking customers to use the self-service options available through myGov and the Centrelink, Medicare and Child Support mobile apps.”

The latest wave of industrial action is a renewed attempt by the CPSU to extract a better offer from the department, which has itself been tied up by the harsh workplace negotiations policies set up under Prime Minister Tony Abbott.

Workers will be taking micro-strikes of 30 minutes at a time.

CPSU National Secretary Nadine Flood said “continuing damage caused by senior management and the Turnbull Government, including through the stalled enterprise bargaining process and the Centrelink robo-debt crisis”, was the reason for the strike.

“The Turnbull Government has rightly been condemned over the Centrelink automated debt debacle, but the problems go far deeper in the Department of Human Services because of years of budget cuts and the Government's harsh and illogical public sector bargaining policy,” the union leader said.

“There are 34,000 hardworking Medicare, Centrelink and Child Support staff who've gone more than three years without a pay rise as they've fought for a new enterprise agreement.

“Budget cuts and the 5,000 jobs that have been slashed from this agency also mean these workers are finding it more and more difficult to provide the quality services that the Australian public needs and deserves.”
