Tomorrow will be another big strike day in Greece.
In Athens there will be no Metro, Bus, Trolley, Tram and Proastiakos (Athens suburban railways). 24 hour strike.
Ilektoriko (Piraeus-Kifissia line, or Metro No. 1) will work between 10 in the morning until 16 in the afternoon.
There won't be no departure/arrival of ships and airplains.
And most of the public sector won't work either. Be well informed before you go anywhere.
