The Socialist government was warned that the European football tournament in France starting on June 10 could face disruptions if the government did not change its stance. Many workers responded to the union's call for protests by halting work at various facilities and setting up roadblocks at ports and distribution hubs. Prime Minister Manuel Valls stated that the government would not retract the law, despite the protests, but suggested that there could be some adjustments to the reforms. The CFDT trade union supported Valls' position. The protests, sparked by labor reforms, were seen as a test of the opposition's strength led by the CGT union. Scores of participants from a youth protest movement known as Nuit Debout joined the street marches, which were organized to express dissent. Police were present to prevent potential violence, as there have been numerous incidents of clashes between police and protesters in recent demonstrations. Union leaders, including CGT chief Philippe Martinez and FO leader Jean-Claude Mailly, expressed their willingness to disrupt the Euro 2016 football contest as a form of protest against the government's policies. Despite calls for changes to the controversial labor law, Prime Minister Valls remained firm in his stance and refused to make any significant alterations. The SNCF national train company reported that around two-thirds of national, regional, and local rail services were operational, indicating that the railworker strikes were having a lesser impact compared to the previous week. Following police action to remove blockades at refineries and fuel distribution centers, Prime Minister Valls stated that 20-30 percent of fuel stations were experiencing shortages. Transport Minister Alain Vidalies stated that the situation had improved, with fuel deliveries from depots to gas stations increasing. The number of fuel stations with shortages decreased from 140 on Wednesday to 83 on Thursday in the Loire-Atlantique region of western France. The French nuclear power capacity was reduced by five gigawatts due to stoppages, which is approximately six percent of the total production capacity of the country. While experts in the power industry believe that the strike at the nuclear plant will not lead to major blackouts because of legal restrictions on strike actions and power imports from other countries, the strike typically increases operating costs for the EDF power utility. Additionally, dockers striking at the southern port of Marseille resulted in an increase in the number of ships waiting at sea to offload oil, gas, and chemicals from five to 21, according to the port authority. A protest over pension reform in 2010 ended after police dispersed pickets at supply depots and railworkers faced stoppages affecting their paychecks. Total SA, a major oil company, has reported that most of its fuel distribution depots are operational, with only one not functioning. However, it has also stated that two out of its five refineries in France are currently not operational, and two more are expected to stop in the near future. The CGT union is facing a more isolated fight this time, as Laurent Berger of the CFDT union, who supports the proposed labor reform, has expressed concern about the intense political and industrial tensions, urging for a more peaceful resolution.
