TEHRAN, Young Journalists Club (YJC) - Thousands gathered in front of UGTT headquarters in central Tunis chanting: "The people want the overthrow of the government". The same slogan was used in 2011 when mass protests toppled strongman Ben Ali and kicked off "Arab Spring" uprisings across the region.
Tunisia is the only Arab country that has undergone a transition to democracy in the wake of those protests, avoiding civil war as in Syria or a return to autocratic rule like Egypt.
But an economic crisis has eroded living standards in the North African country and unemployment is high as political turmoil and lack of reforms have deterred investment needed to create jobs. That has forced the government to launch austerity measures to please donors and lenders including the International Monetary Fund.
The one-day strike hit airports, ports, schools, hospitals, state media and government offices. At Tunis Carthage airport, most flights were canceled and check-in counters closed, leaving hundreds of angry passengers stranded.
"The power belongs to the people", protesters chanted at a central UGTT rally near the central Habib Bourghiba Avenue, the scene of mass protests in 2011, also calling for salary increases. Police showed a strong presence but did not interfere.
Tunisia is under pressure from the IMF to freeze public sector wages as part of measures to reduce its budget deficit.
The public sector wage bill has doubled to about 16 billion dinars ($5.5 billion) in 2018 from 7.6 billion in 2010.
But the UGTT says the monthly average wage of about $250 is one of the lowest in the world, while the state Institute of Strategic Studies says real purchasing power has fallen by 40 percent since 2014.
Sami Tahri, Deputy Secretary-General of the UGTT, said the government had opted for a confrontation with public servants in a bid to meet the IMF's demands.
