Greek unions are preparing a 48-hour strike for the next week, the country's largest trade union association GSEE announced on Thursday.
The strike is scheduled for June 28-29 to coincide with a debate in the parliament on new austerity measures, the medium-term saving program of almost 30 billion euros by 2015.
Thousands of demonstrators have been protesting outside parliament for the past three weeks.
If GSEE is joined by the largest union of state employees, ADEDY, as has happened in the past, the strike will affect all government agencies, including public transport and possibly domestic and international flights.
