PARIS (Reuters) - French hardline trade union CGT said on Wednesday that strikes had reduced output at one of Total's <TOTF.PA> oil refineries in France and disrupted product deliveries, although the company said the action was having little impact.
The French oil and gas major said only product deliveries from its Normandy platform were affected and measures were in place to limit the impact on clients.
Total operates four out of France's seven refineries.
A spokesman for CGT, which called the two-day strike over pay and bonus disputes, said two of Total's refineries were affected and workers at the other two would decide later on Wednesday and early on Thursday whether to join the action.
CGT's Thierry Defresne said the strike started at Total's 109,000 barrel-per-day (bpd) Feyzin refinery at 2100 GMT on Tuesday. Following negotiations with local managers, both sides agreed to decrease output.
Defresne did not say by how much output was curbed, but added that the situation would continue until Thursday afternoon.
"Products expeditions were halted temporarily at Feyzin," he added.
Defresne said workers at Total's 253,000 barrel-per-day Gonfreville refinery in Normandy voted to start the strike on Wednesday morning and they were joined by colleagues from the petrochemicals section of the platform.
"No products loading and deliveries were taking place at Normandy, and crude deliveries to the refinery have also been halted," he said.
