The planned general strike for later today, 10 December is still scheduled to go ahead, but unions bowed to the government and called off protest marches amidst Greece's worst rioting in decades.
2.5 million workers in the GSEE and ADEDY general unions, comprising around half of Greece's total workforce are to strike today.
They are demanding an end to cuts in public spending and attacks on pay and pensions.
Greece's transport network in particular is set to grind to a halt, as many airlines have already cancelled all flights in and out of the country.
Tens of thousands of workers are expected to pour into the streets, already ravaged by days of clashes over the murder of a teenage boy by police.
