Ships docked at Greek ports, and railway and bus services were disrupted on Wednesday as workers from different branches, from transport and construction to hospital physicians and teachers, joined a nationwide strike to protest squeezed living standards and seek higher pay.

Many Greeks saw their wages and pensions slashed in return for bailouts worth 280 billion euros ($297 billion) during a 2009-2018 debt crisis, which shaved a quarter off Greece's economic output and nearly pushed the country out of the eurozone.

With the Greek economy recovering firmly since 2018, Prime Minister Kyriakos Mitsotakis' center-right government has raised the minimum monthly gross wage four times since taking power in 2019 to 830 euros a month and has promised to raise it further to 950 euros by 2027.

But Greeks say the rises are not enough and their salaries – which still lag the European average – do not last them a month as energy, food and housing costs rose faster.

"Prices and rents have skyrocketed, while wages are at a low point," read the poster of GSEE, Greece's largest private sector union, which called for immediate and substantial pay rises for workers struggling with what it said was an unprecedented cost-of-living crisis.

GSEE – representing some 2.5 million workers in Greece – also asked for government action against oligopolies, which it blamed for concerted practices that drove the cost of basic goods higher.

Workers were expected to protest in central Athens later on Wednesday.

Mitsotakis acknowledged on Monday there was room for improvement concerning wages and gross domestic product (GDP) per capita and reiterated a call to the EU to help with discrepancies in power prices that he said saw Greeks paying far more than other countries in the bloc.

The strike comes as the government submits later on Wednesday its final 2025 budget to the 300-seat Parliament for debate before a vote due next month.

The draft budget sees economic growth of 2.3% next year and higher tax revenues thanks to expanding digital payments and booming property sales.
