Tunisia’s powerful public sector union, the UGTT, has called nationwide strike action that is scheduled to begin in the weeks ahead.
It says this is partly in response to the government’s privatisation plans.
The authorities have suggested selling off loss-making, State-owned enterprises.
The union’s members are also unhappy at high levels of inflation and the lack of progress in pay talks.
Tunisia is widely regarded as having made important social and democratic gains following its Arab Spring revolution in 2011.
But successive governments have struggled to tackle the country’s deep economic problems.
