Thousands on strike across Craigavon
The strike is affecting education, public transport and administration.
Many schools were off and hospital staff also joined picket lines.
John Creaney of Unison said he was pleased with the turnout at Craigavon Area Hospital where the picket was staged at the roundabout.
He said the reason for the strike was the budget cuts and called for more health staff on the front line.
He defended the fun day atmosphere at the picket line where there was an inflatable ‘pub’ and barbeque. He said the union wanted to get the public on their side and support their calls for an end to austerity measures.
Jim Kelly of Unite said: “Austerity will devastate Northern Ireland’s economy – an economy underpinned by public sector consumption. Austerity will only exacerbate sectarian divisions pitting one community against the other in a desperate contest for resources.
“We do not accept blaming the Tories is a justification for administering these cuts. Our local political leaders are joined at the hip in their demand for the power to slash corporation tax rates through decimating funding for public services by – at the very least - a further £325 million a year.”
