It cautioned the Socialist government that the European football competition starting in France on June 10 could face disruptions if the government did not compromise. Demonstrators flooded the streets while workers heeded the union's call by halting operations at various facilities and setting up obstacles at ports and distribution centers. Prime Minister Manuel Valls remained firm on the law reforms, stating that there could be minor adjustments but no major changes. The CFDT trade union supported Valls' stance. The ongoing protests against the reforms, which aim to simplify hiring and firing processes, were seen as a crucial test to determine the strength of the CGT-led opposition. Scores of marchers from the Nuit Debout youth protest movement joined the street marches. Police were deployed to prevent fringe violence, as several protesters and 350 police officers had been injured and over 1,300 arrested at similar rallies in recent weeks. CGT chief Philippe Martinez suggested that the government could halt the Euro 2016 football contest to resolve the situation. Jean-Claude Mailly, leader of the FO union, called for the prime minister to take action as a Paris march commenced. Despite calls to scrap the controversial part of the law that sparked the protests, Prime Minister Valls insisted there would be no change in direction. The SNCF, a state train company, reported that more than two-thirds of national, regional, and local rail connections were operational, indicating that the railworkers' strikes were having a lesser impact compared to last week when the number of trains running was cut in half. Following police intervention to clear blockades at refineries and fuel distribution depots, Prime Minister Valls stated that 20-30 percent of fuel stations were either out of fuel or low on certain types of fuel. Transport Minister Alain Vidalies mentioned that the situation was improving, with fuel deliveries from depots to petrol pumps increasing. The number of fuel stations experiencing shortages decreased from 140 on Wednesday to 83 on Thursday in the Loire-Atlantique department of western France. The French nuclear power capacity has been reduced by up to five gigawatts because of stoppages, which is approximately six percent of the total production capacity of the country. Despite experts in the power industry stating that the strike at the nuclear plant is not likely to cause major blackouts due to legal restrictions on strike activities and power imports from other countries, it usually leads to higher operating costs for the EDF power utility. Additionally, with dockers on strike at the southern port of Marseille, the number of ships waiting at sea to unload oil, gas, and chemicals has increased to 21 from the usual five, according to the port authority. In 2010, a protest over pension reform ended when police dispersed picketers at supply depots and railworkers faced stoppages affecting their income. Total SA, a major oil company, announced that all of its fuel distribution depots, except for one, were operational. However, it cautioned that two out of its five refineries in France were currently not in operation, with two more expected to shut down in the near future. The CGT union is facing a more isolated struggle this time around. Laurent Berger, leader of the CFDT union which supports the proposed labor reform, expressed concerns about the tense political and industrial relations environment, urging for a more peaceful approach.
