A coordinated general strike, scheduled for next Wednesday, 3 June, threatens to paralyse the country's main mobility networks and compromise international connections, creating significant instability at a time when the country is welcoming the first major influx of tourists of the early summer season.

Affecting various services

According to union sources, the strike will simultaneously involve cabin crew, railway personnel, urban public transport operators, and medical service professionals.

The most dramatic impact of the protest is expected to be felt in the national airspace. Industry estimates indicate that more than 500 flights could be cancelled or suffer significant delays throughout the day, severely affecting the operations of the flag carrier TAP Air Portugal, as well as those of Portugália and SATA.

This new wave of disruptions comes at a critical time for Lisbon's airport infrastructure, which was already under considerable pressure and experiencing long queues due to the recent logistical implementation of the new European Union Entry/Exit System, threatening to exacerbate the chaos at airport terminals.

Compromising urban mobility

In major metropolitan areas, urban mobility will also be compromised.

Workers affiliated with FECTRANS will proceed with protest actions expected to paralyse or severely limit the Lisbon Metro, extending the constraints to the Tagus River connections and the public transport network in the city of Porto.

At the heart of this mass protest is the unions' strong opposition to the labour reform proposals presented by the Executive, which include measures to make dismissal rules more flexible and expand the use of outsourcing, initiatives that aviation representative bodies classify as a serious setback to workers' rights and protections.

Given the imminent threat posed by this blockade, travel insurance experts have issued a clear warning to passengers, emphasising that coverage policies vary considerably among insurers.

Many operators exclude compensation for disruptions resulting from strikes that were foreseeable or public at the time of booking.

In this context, the recommendation is to immediately review contractual conditions and contact airlines directly to assess alternative flight options in 2026, when global demand for air travel continues to break records but a lack of infrastructure capacity threatens to stifle tourism growth.
