The main union representing Public Power Corporation workers, GENOP-DEI, said on Monday that its members will hold a 24-hour strike on Thursday, January 31.
The union said it was taking the action in support of metro, tram and electric railway workers in Athens who were forced to return to work on Friday after a nine-day strike over wage cuts.
The public transport workers were issued with civil mobilization orders by the government.
GENOP-DEI said that the measure was “illegal, undemocratic and unconstitutional”.
It is not clear if the strike threatens to cause any power outages.
