Greece?s two main labor unions called a 48-hour strike on Thursday to protest the austerity measures in Greece?s potential loan agreement with the European Union and the International Monetary Fund.
The strike, which will affect public transport today and tomorrow, will be accompanied by three days of demonstrations.
Today and tomorrow, rallies will be held in central Athens from 11 a.m.
On Sunday, there are plans to hold a protest from 5 p.m., possibly to coincide with a vote on the terms of the loan agreement in Parliament.
Greece?s two largest unions — GSEE, representing the private sector, and ADEDY, representing the public sector — have backed the action.
There will be no public transport apart from the Kifissia-Piraeus electric railway (ISAP) between 10 a.m. and 5 p.m.
Ferries will also remain in port.
