Greece will grind to a halt on Wednesday in a 24-hour general strike against plans by the conservative government to introduce a 13-hour workday.
Transport in Athens, trains and ferry services will be disrupted while teachers, hospital staff, and civil servants are also taking part in the mobilisation.
Protests are planned around midday (0900 GMT) across the country to oppose the reform advocated by the conservative government of Kyriakos Mitsotakis.
The main private sector union GSEE, which is spearheading the walkout alongside public sector union ADEDY, has said the reform “endangers the health and safety of workers and destroys the balance between professional and personal life”.
Pro-communist union PAME has accused the government of seeking to introduce “modern slavery” for workers
