Workers in French Polynesia belonging to a key union are planning to strike this week.
More than eight thousand employees belonging to the territory's second biggest union are due to take action over pay claims.
The siutation is being inflamed by the ongoing political uncertainty.
At the end of last week, the French High Commissioner to Tahiti, Michel Mathieu, declared in an official communique that Gaston Flosse was the legal President.
He said none of the legal challenges put forward by Oscar Temaru would be strong enough to oust Mr Flosse.
France's highest administrative court is to sit this week to ascertain whether territorial elections in May were lawful.
It has two weeks to decide on a series of appeals in connection with the political crisis in French Polynesia.
