Workers at France's main airport operator ADP said they would remove a strike notice for the weekend, as did the firefighters at Paris's international Charles de Gaulle airport the day before, a union source told Reuters.

That decision, on top of the firefighters' one, means major disruptions are not likely to happen this weekend, which marks the start of the French summer vacation period.

"I remain cautious but there have been very important talks, supported by the state, between the workers and the management, at ADP, also at (railway operator) SNCF, that led to purchasing power measures", French Transport minister Clement Beaune told BFM TV earlier on Friday.

"We're still working closely with ADP to ensure everything goes smoothly at the start of the summer vacation. We will do everything to avoid strike actions during the summer (...) I am confident," he added.
