Some 100,000 people took to the streets across the Republic of Ireland against austerity on Saturday of last week.
The largest protest was in Dublin where 60,000 joined the march.
The Irish government rushed a bill through parliament last week.
It signed up to a “promissory note” meant to ensure that the government does not default on debt created by the bailout of the banks.
People Before Profit MP Richard Boyd Barrett says people are fed up. He expects opposition to grow.
“The deal is a hoax, it’s a puff of smoke,” he said.
“Nothing has changed. In fact, if anything, the debt has been firmly pinned to the backs of ordinary people.
“I think today’s demonstration proves ordinary people in this country haven’t been fooled by the hype.”
There was much bitterness on the demonstration, and some frustration that the unions may sign up to another national deal on cuts with the government.
Teacher Patrick Healey has seen his wages cut by £600 a month, or 20 percent, in the last five years.
“They want us to pay all their bills and we’re getting tired of it now,” he said.
