Strike may stop all public transport

On 12 May 2010 public and private sector unions announced plans to stage a one-day nationwide strike on 20 May to protest the government's austerity measures. The industrial action is expected to cause disruptions to transportation and other services. Flights to and from Greek airports will likely be halted during the strike action. The work stoppage is the fourth nationwide strike called in 2010 over the government's economic austerity measures, which include reforms to the pension system. Meanwhile, Greece's two main umbrella unions organized a joint rally at Klafthmonos Square in Athens on 12 May to protest the measures; thus far there have been no reports of violence or arrests.
