Medical staff, nurses, and administrative workers at the Lisboa Ocidental Local Health Unit (ULSLO) are threatening industrial action following the disappearance of thousands of overtime hours from the computer system. Unions representing the staff have scheduled a meeting with the administration for the 19th to address long-standing issues, including unpaid overtime, career progression delays, and failures in performance evaluation systems. If negotiations fail, workers have approved a motion to proceed with a strike. Meanwhile, the Health Inspectorate is investigating the unit's Human Resources department regarding the legality of recent hiring practices.
