It was cautioned by the Socialist government that the European football tournament beginning in France on Jun 10 could face interruption if the government did not compromise. Demonstrators filled the streets as workers heeded the union's call to halt work at various facilities and set up roadblocks and fires at ports and distribution centers. Prime Minister Manuel Valls stated that the government would not retract the law and would dismantle refinery blockades, although some adjustments to the reforms could be made. The CFDT trade union supported Valls' stance. The protests on Thursday, following months of demonstrations against labor reforms, were seen as a test of the strength of the CGT-led opposition. Scores of participants from the youth protest movement Nuit Debout, also known as Night Rising, joined the street marches. Police were present to prevent any fringe violence, as previous rallies had resulted in injuries to 350 police officers and protesters, along with over 1,300 arrests. When asked if the CGT union was willing to disrupt the Euro 2016 football contest, Philippe Martinez responded by saying the government could stop the clock to resolve the situation. Jean-Claude Mailly, leader of the FO union, expressed discontent at the beginning of a Paris march, stating that it was time for the prime minister to take back the red card. Despite calls to scrap the controversial part of the law that sparked the protests, Prime Minister Valls remained firm in his stance, rejecting any changes to the legislation. The SNCF national train company reported that a majority of national, regional, and local rail services were operational, indicating that the railworkers' strikes were having less of an impact compared to the previous week. Following police actions to remove blockades at refineries and fuel distribution centers, Prime Minister Valls stated that 20-30 percent of fuel stations were either out of fuel or facing shortages. Transportation Minister Alain Vidalies expressed that the situation had improved, with fuel deliveries from depots to stations on the rise. The number of fuel stations experiencing shortages in the Loire-Atlantique region of western France decreased from 140 on Wednesday to 83 on Thursday, according to local government officials. 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 power industry experts believing that the strike at the nuclear plants will not lead to major blackouts due to legal restrictions on strike actions and imports of power from other countries, it typically increases operating costs for the EDF power utility. Additionally, there was a strike by dockers at the southern port of Marseille, causing the number of ships waiting at sea to offload oil, gas, and chemicals to increase to 21 from the usual five, as reported by the port authority. In 2010, a protest over pension reform ended when police dispersed pickets at supply depots and railworkers faced interruptions that affected their salaries. Total SA, an oil company, reported that most of its fuel distribution depots are operational except for one. However, it cautioned that two out of its five refineries in France are currently not operating, with two more expected to stop in the near future. The CGT union is facing a more isolated struggle this time around. Laurent Berger, leader of the CFDT union and supporter of the proposed labor reform, expressed concerns about the tense political and industrial atmosphere, calling for a more peaceful approach.
