PARIS — Uncollected trash rotting on the streets of Paris. Strikes on trains that go to the national stadium and on planes that should be carrying fans. With the eyes of Europe and the world turning to France for the European Championship, the host nation isn't putting on its best face.

A tug of war between the Socialist Party government and labor leaders over changes to French workplace practices is ensnaring fans hoping for a month of fine soccer and a great time.

On Thursday, strikes threw train services to the Stade de France into disarray before the opening game it hosts tonight.

For today, railway and Metro authorities promised extra trains to bypass the strikers and carry 70,000 people — as many as with any normal match — to the stadium in the hours immediately before and after the game, to and from central Paris. The remaining 10,000 of the 80,000 spectators are expected to come by road.

Strikes also are planned from Saturday on the national air carrier, Air France. In swanky Paris neighborhoods, overflowing garbage containers spewed stinking bags of trash onto the streets, uncollected by strikers.

Both the government and labor leaders warned fans to brace for hardship.

“The strike, clearly, will disrupt the Euros,” said Beranger Cernon of the left-wing General Confederation of Labour union, leading strikers at the Gare de Lyon, one of Paris' main rail hubs. “We will continue to strike.”

Using the arrival of Euro 2016 to ratchet up pressure on the government is the latest step in an extensive protest movement against a labor bill that will loosen workplace protection. Recent weeks also have seen violent demonstrations and fuel shortages. At least 2 million foreign visitors are expected for the 24-nation tournament, Europe's biggest sports event since terror attacks in Paris in November and in Brussels in March.

The government's minister for towns, youth and sports accused strikers of “guerrilla” tactics and of making France look bad and suggested that Paris' bid for the 2024 Olympic Games could be undermined as a consequence.

Air France said 20 percent to 30 percent of its flights would be canceled Saturday, the second day of the competition, because of a pilots' strike.

CEO Frederic Gagey told reporters the carrier offered a new proposal in a long-running dispute over working conditions, but unions rejected it.

There was a silver lining: Clouds but no rain are forecast for the skies above the Stade de France tonight.
