Argentina Postpones Airport Strike After Government Warning

On September 3, 2026, Argentina's state aviation workers, represented by the union Asociacion de Trabajadores del Estado (ATE), postponed a planned 48-hour airport strike. The union had intended to halt operations at over 27 airports across the country over two days, with flights scheduled to run on a reduced schedule during the strike period. However, the government intervened, prompting ATE to call off the strike temporarily.

ATE warned that it could resume the strike on September 7 if negotiations with the Labor Ministry failed to produce an agreement. The union's assistant general secretary, Mercedes Cabezas, expressed willingness to engage in talks, emphasizing the need for stable pay to ensure safe and reliable flights. However, the union also threatened to relaunch the strike if the government did not pay agreed-upon salary increases and reopen sectoral collective bargaining.

The Labor Ministry convened a meeting to clarify how the essential-service rule applied to ANAC staff, which covers ground traffic coordinators, airport firefighters, safety inspectors, health and emergency staff, and administrative workers. ANAC, Argentina's civil aviation authority, oversees civil aviation safety, airport operations, and air traffic coordination.

Under Argentina's classification of air navigation as an essential public service, unions must guarantee a minimum level of service during any stoppage, which in this case was set at 75 percent of normal air services.

ATE demanded that the government guarantee at least 75 percent of normal air services during the strike and covered flights, though commercial flights could still face delays or cancellations. The government's minimum coverage requirement applied to flights already in progress, but not to those in progress. Passengers were advised to check their itineraries with airlines, as the strike could still disrupt travel plans.

ATE's legal team met with provincial union coordinators before announcing the strike's postponement, describing it as a temporary pause. The union requested that the Labor Ministry formally define the scope of the essential-service rule for ANAC staff, triggering a meeting between the two parties. The 48-hour airport strike, initially announced on September 1, was set to run from September 3-4, with flights expected to run normally outside the strike windows of 09:00-12:00 and 18:00-21:00 local time.
