The French government fought back Friday in a bitter labour dispute with unions, sweeping away blockades at fuel depots after President Francois Hollande vowed to “stand firm” over the reform that sparked the industrial action.

Authorities stepped up their offensive at dawn, when riot police swept away a blockade of burning tyres at an oil depot near a Total refinery in Donges, western France.

Police cleared all 15 blockades around the country, leaving only one depot still shut by a strike.

“Unblocking these depots will allow an increase in delivery capacity to resupply more and more petrol stations,” a transport ministry spokesman said.

Six of France’s eight oil refineries were also still either closed or operating at reduced capacity due to ongoing union action.

The stoppages are part of a wave of strikes and mass demonstrations that have seriously disrupted France, just as it gears up to host the Euro 2016 football championships in two weeks’ time.

A defiant Hollande, in Japan for a G7 summit, said he would not bend to the unions’ demands to withdraw the reforms that the Socialist government hopes will free up France’s famously rigid labour market.

“I will stand firm because I think it is a good reform,” he told reporters.

The president said the government’s top priority was to ensure the “normal functioning of the economy” in the face of some of the most severe industrial action for two decades.

Strikes also continued at nuclear power stations — which provide three-quarters of the country’s electricity — but have so far failed to affect supply, authorities said.

The employers’ federation, Medef, expressed growing anger over the effect the strikes are having on France’s fragile economic growth.

Medef chief Pierre Gattaz condemned the “thugs’ methods” of the unions and urged the government to “resist their blackmail”.

– Tourist bookings affected –

Tourist bookings were also being hit and hoteliers fear Euro 2016 visitors will be put off by the industrial action.

“A strike of this size a few weeks before Euro 2016 and right in the middle of the tourist season is completely unacceptable,” the GNI hotel industry federation said in a statement.

Small business owners were feeling the pinch too.

“It’s not good for business. I support helping people but not people who do nothing,” said Guillaume Bouvelot, 51, who owns a snack bar in an affluent district of Paris where customers were thin on the ground.

But all the main unions were going for broke against Hollande’s deeply unpopular government, urging workers to “multiply and support” the strikes.

They criticised the government’s “stubbornness” in refusing to withdraw the contested law, saying it was only “boosting the determination” of protesters.

Hollande responded that dialogue was “always possible”, but not if the government was threatened with “an ultimatum”.

The mounting problems for the government come a year ahead of an election in which Hollande is considering standing again despite poll ratings that are among the lowest for a French leader in modern history.

– Street violence –

The CGT union that has led the protests has called for rolling strikes on the Paris Metro network to start on June 10, the day of the opening match of Euro 2016, giving the organisers new headaches on top of security concerns sparked by last November’s jihadist attacks in Paris.

Tens of thousands of activists staged a demonstration in Paris on Thursday that descended into violence.

Riot police used tear gas after masked youths smashed windows and damaged cars in the latest outburst of anger over the controversial legislation.

Authorities said 62 demonstrators were taken into custody, while 15 policemen were injured.

Many organisations, including the International Monetary Fund, have said the labour reforms are necessary to create jobs in a country where around 10 percent of the workforce are idle.

But the CGT is furious that the government forced the legislation through parliament without a vote and is demanding it be scrapped altogether.

Unions argue the reforms favour business at the expense of workers’ rights and are unlikely to bring down high unemployment.

Prime Minister Manuel Valls, fighting for his political survival, has insisted the legislation will not be withdrawn, but says it might still be possible to make “changes” or “improvements”.
