A meeting has been called in New Caledonia today between the government and striking workers of the Koniambo nickel plant.
This follows a stoppage at the plant last week over the planned dismissal of 41 local employees as part of a company restructure.
The unions said it was not normal to go ahead with the sackings after significant sums had been made available to support the multi-billion US dollar plant.
Last week, one of the main investors, Glencore, said the second furnace would be rebuilt but it also said the planned dismissal would still go ahead.
Last month, the French prime minister Manuel Valls confirmed to the president of New Caledonia's northern province Paul Neaoutyne that the power plant for the Koniambo smelter would benefit from concessions worth more than $US200 million.
Koniambo insists the restructure was approved by all parties concerned.
