(ANSA) - ATHENS - Greece is paralyzed by a general strike called by the largest private and public sector unions against a pension reform proposed by the Tsipras government. At around midday, workers including employees, the self-employed, farmers and pensioners will demonstrate in downtown Athens and then march towards Parliament. Many categories are protesting against a hike in social security payments and taxes, which will affect 75-80% of these categories' salaries, according to unions.

Public transportation stopped working on Thursday both in city and in outer areas while members of unions representing professionals, artisans and retailers (Gsevee) will also strike.

The Confederation of trade and enterprise (Esee) is also adhering to the protest.

Lawyers, notaries, truck drivers, gas station attendants, doctors and pharmacists are among those expected to demonstrate.

Maritime transport workers will strike for 48 hours until Saturday morning. (ANSA)
