The General Union of Tunisian Workers has called for a nationwide strike in an attempt to pressure the country's interim government into resignation as the cabinet is preparing for a reshuffle, Press TV reported.
The strike is urged on Wednesday and thousands of people are expected to walk out of their jobs in Tunisia's second biggest city, Sfax, a Press TV correspondent reported on Tuesday.
This comes as the transitional government announced on Tuesday that it is bracing for a shake-up which may endanger at least six ministerial posts.
The government is apparently abating people's outrage who are holding street protests in the capital city, Tunis, against the inclusion of the supporters of the overthrown President Zine El Abidine Ben Ali in the new governing team.
Hundreds of people have camped for a third day outside the office of Prime Minister Mohammed Ghannouchi, urging the dissolution of Ben Ali's former ruling party of Constitutional Democratic Rally (RCD). The premier was the former president's right-hand man.
Teachers and students have also joined the street protests, starting an open-ended strike.
Political sources, on the other hand, said that Tunisia's politicians were trying to set up a committee of "wise men" to replace the interim government, having been in charge since January 14, when Ben Ali was toppled in a revolution and fled to Jeddah in Saudi Arabia.
