Tens of thousands of Greeks took to the streets of Athens on Wednesday as part of a nationwide strike against austerity that confined ferries to ports, shut schools and left hospitals with only emergency staff.
Beating drums, blowing whistles and chanting, "Robbers, robbers!" more than 60,000 people angry at wage cuts and tax rises marched to parliament in the biggest protest for months over austerity policies required by international lenders.
In the capital, riot police fired tear gas at hooded youths hurling rocks and bottles during a demonstration, mostly of students and pensioners, which ended peacefully.
The two biggest labor unions brought much of crisis-hit Greece to a standstill with a 24-hour protest strike against policies they say deepen the hardship of people struggling through the country's worst peacetime downturn.
Representing 2.5 million workers, the unions have gone on strike repeatedly since a debt crisis erupted in late 2009, testing the government's will to impose the painful conditions of an international bailout in the face of growing public anger.
"Today's strike is a new effort to get rid of the bailout deal and those who take advantage of the people and bring only misery," said Ilias Iliopoulos, secretary general of the ADEDY public sector union, which organized the walkout along with private sector union GSEE.
"A social explosion is very near," he told Reuters from a rally in a central Athens square as police helicopters clattered overhead.
The eight-month-old coalition of Prime Minister Antonis Samaras has been eager to show it will implement reforms promised to the European Union and International Monetary Fund, which have bailed Athens out twice with over 200 billion euros.
The government has cracked down on striking workers, invoking emergency laws twice this year to get seamen and subway workers back to work after week-long walkouts that paralyzed public transport in Athens and led to food shortages on islands.
Demonstrations were also held in Greece's second-biggest city, Thessaloniki, and on the island of Crete where dozens of protesters hit the streets waving black flags.
In Athens, crowds began to disperse from Syntagma Square outside parliament, but minor clashes between riot police and hooded youths moved to sidestreets.
Labor unrest has picked up in recent weeks. A visit by French President Francois Hollande in Athens on Tuesday went largely unreported because Greek journalists were on strike.
"The period of virtual euphoria is over," said opposition leader Alexis Tsipras, whose Syriza party has regained a narrow opinion poll lead over the governing conservatives.
"Those who thought Samaras would renegotiate the terms of the bailout ... are now faced with the harsh reality of unpaid bills, closed shops and lost jobs," he said.
Anger at politicians and the wealthy elite has been boiling during the crisis, with many accusing the government of making deep cuts to wages and pensions while doing too little to spread the burden or go after rich tax evaders.
"This government needs to look out for us poor people as well because we can't take it any more," said Niki Lambopoulou, a 43-year-old insurance broker and single mother.
"I work night and day to make ends meet and the government is killing our children's dreams."
In a sign it may be buckling under pressure, the government announced on Monday it would not fire almost 1,900 civil servants earmarked for possible dismissal, despite promising foreign lenders it would seek to cut the public payroll.
"The strike highlights the growing gap between the plight of ordinary Greeks and the demands of Greece's international creditors," said Martin Koehring, analyst at the Economist Intelligence Unit, forecasting more social unrest this year.
Greece secured bailout funds in December, ending months of uncertainty over the country's future in the euro zone, and analysts said this had created expectations among Greeks that things would improve for them personally.
"If these expectations are not satisfied by the summer, then whatever is left of the working class will respond with more protests," said Costas Panagopoulos, head of Alco pollsters.
Six years of recession and three of austerity have tripled the rate of unemployment to 27 percent. More than 60 percent of young workers are jobless.
Most business and public sector activity came to a halt with schoolteachers, train drivers and doctors among those joining the strike. Banks pulled down their shutters and ships stayed docked as seamen defied government orders to return to work.
"I'm on the brink of going hungry. My life is misery," said Eleni Nikolaou, 60, a civil servant who supports her unemployed brother on her reduced wage. "If this government had any dignity it would resign. I want them to leave, leave, leave."
