Greece's two main unions for the public and private sectors said they would hold a joint rally in Athens on Wednesday against the government's 'unjust and harsh' austerity measures. 'The country's workers are mantaining the struggle and their opposition to the package of unjust and harsh measures by the government, the European Commission, the European Central Bank and the International Monetary Fund,' the private sector GSEE union said in a statement on Monday. There have so far been three general strikes in opposition to the measures which the government enacted to clinch a 110-billion-euro (140-billion-dollar) bailout loan to tackle Greece's debt crisis.
