The Lisbon Metro is closed this Thursday, April 9, due to a 24-hour workers' strike, leading to overcrowding on other public transport services such as buses. Union leader Sara Gligó stated that the strike, which involves specific professional categories, is not about salary increases but rather concerns working conditions, training, and allegations of workplace harassment. No minimum services were decreed for this strike or for the next one scheduled for April 14, with the exception of essential safety and maintenance tasks.
