Workers at two of the 12 oil refineries in France have voted to end their strike over plans to raise the state pension age.
Employees are also returning to work at a third refinery closed by a dispute that was not part of a national wave of protest against the government's pension plans.
Oil industry representatives say all 200 supply depots have been cleared of pickets and are operating normally.
The strikes led to serious fuel shortages.
The BBC reports the government hopes this could be a turning point in the dispute.
Parliament is expected to bring into law on Wednesday an increase in the minimum retirement age from 60 to 62 and set the threshold for full pension payments at 67.
But unions have called another day of national strikes on Thursday and students are due to stage further protests on Tuesday.
The government warned on Monday that the disruption was threatening the country's economic recovery.
Finance Minister Christine Lagarde said the strikes were costing France between 200 and 400 million euros a day.
