The air traffic controllers union announced that it had failed to reach an salary agreement with the state-run Argentine Air Navigation Company (EANA) and that it would resume strikes in February. At time of writing, no dates had been given for when that will happen. The Association of Air Navigation Security and Protection Technicians and Employees (ATEPSA) union had already staged a series of strikes in December due to failed wage negotiations. The announcement of more strikes comes as the time period mandated by the government order has now expired. Air traffic controllers are a key part of aeronautical operations, as they are responsible for supervising traffic from control towers and area control centers, coordinating aircraft separation, and guiding both takeoffs and landings.
