Public sector workers in Greece struck on Thursday and Friday of last week against massive job cuts.
The government plans to suspend 25,000 workers by the end of the year. They could then be transferred or sacked.
Workers marched in Athens on Thursday. The government sneaked legislation granting it sweeping new powers onto a vote about building regulations in parliament that evening.
It can now merge or abolish public sector organisations by presidential decree without a vote in parliament.
State archaeologists protested at the Acropolis after an announcement that 500 workers would be suspended at the culture ministry.
Teachers burned their suspension letters. They plan an all-out strike when school starts early next month.
Union leader Themis Kotsifakis was among the 2,122 teachers to be suspended. The union leadership had called off a planned strike during exams that could have caused major disruption.
Opposition to the closure of state broadcaster ERT in May split the government.
It now has a razor-thin majority. And it has many more cuts still to force through.
