Portugal Airport Strike: Menzies Ground Handling Workers Plan Seventy Six Days of Disruptions- What travellers need to Know

Travelers planning to pass through Portuguese airports should brace for significant travel disruptions. Ground handling staff employed by Menzies Aviation, which provides services at major airports across Portugal, have announced a series of strikes set to last until January 2026. These labor actions are expected to affect key airports, including Lisbon, Porto, Faro, Madeira, and the Azores, with disturbances scheduled for high-traffic travel periods such as long weekends, Christmas, and the New Year.
Strike Schedule and Duration
The industrial action by Menzies ground handling workers will unfold over several months, with the first wave of strikes beginning on September 3, 2025, and continuing in phases until January 2026. The unions involved, SIMA (Union of Metal and Related Industries Workers) and the Transport Union (STA), have carefully planned these strikes to coincide with peak travel dates, potentially causing widespread disruptions during crucial periods such as long weekends, holiday seasons, and international travel peaks.
The scheduled strike dates are as follows:
- September 3–9, 2025
- September 12–15, 2025
- September 19–22, 2025
- September 26–28, 2025
- October 3–6, 2025
- October 10–13, 2025
- October 17–20, 2025
- October 24–27, 2025
- October 31–November 3, 2025
- November 7–10, 2025
- November 14–17, 2025
- November 21–24, 2025
- November 28–December 1, 2025
- December 5–8, 2025
- December 12–15, 2025
- December 19, 2025–January 2, 2026
These dates have been specifically selected to maximize impact during times when airports experience heavy passenger traffic. Passengers flying through Portugal during these months can expect potential delays and service disruptions, particularly during the holiday season when airport traffic is at its peak.
Reasons for the Strike
The decision to strike comes as workers at Menzies demand improvements in their working conditions, including an increase in basic salaries to meet or exceed Portugal’s minimum wage. Workers are also seeking better compensation for night shifts, as well as the enforcement of previously agreed-upon benefits. SIMA and STA, the two unions organizing the action, have argued that current conditions at the company violate labor laws and fail to provide adequate compensation for workers, who are facing increasing economic challenges.
In addition to wage issues, the unions are calling for greater respect for labor agreements that were signed in the past. They are particularly concerned about Menzies’ failure to meet commitments regarding job benefits and working conditions. Union leaders have emphasized that these issues are not isolated incidents but part of a broader struggle for fair treatment within the aviation sector in Portugal.
The unions have also expressed frustration with the company’s management, as well as with the broader industry’s approach to labor relations. They claim that the airline companies and Menzies management have failed to engage in meaningful negotiations or take the workers’ concerns seriously. The unions have stressed that these strikes are a direct response to what they see as management’s neglect of workers’ rights and needs.
Impact on Airport Operations
The strikes are expected to affect ground handling operations across multiple airports in Portugal, including key hubs such as Lisbon’s Humberto Delgado Airport and Porto’s Francisco Sá Carneiro Airport. Ground handling services such as check-in, baggage handling, and boarding are expected to be severely disrupted during the strikes, leading to delays and cancellations of flights.
However, the Portuguese government has ordered minimum service levels in an attempt to ensure that essential operations continue. According to a decree by the Court of Arbitration of the Economic and Social Council, a significant portion of the ground handling operations will be required to continue, though services will be reduced during the strike periods. This includes 100% of ground handling services for domestic and island flights, but only 35% for international flights.
Despite the minimum service decree, unions have criticized the decision, arguing that the measures in place will not allow workers to effectively demonstrate their grievances. They believe that the minimum service levels compromise the strike’s effectiveness and undermine the workers’ ability to force management to address their demands.
Recommendations for Travelers
Given the ongoing disruptions, travelers are encouraged to take proactive steps to minimize the impact of the strikes on their travel plans:
- Check Flight Status Regularly: It is crucial to stay updated on any potential flight delays or cancellations. Airlines and airports are expected to issue regular updates.
- Arrive Early: With additional delays expected at check-in and security, passengers should plan to arrive well in advance of their flight departure times.
- Consider Alternative Routes: If possible, consider flying from airports outside Portugal or use alternative transportation options to reach your destination.
- Pack Light: To avoid further delays caused by baggage handling issues, it is advisable to travel with hand luggage only, if feasible.
- Stay Informed: Follow updates from your airline, the airports, and official sources such as government websites for the latest information on the status of the strikes and airport services.
By staying informed and prepared, passengers can help ensure that their travel plans are impacted as little as possible during the strike period.
Conclusion
The labor dispute at Menzies Aviation in Portugal is set to cause considerable disruptions for travelers over the coming months. The strikes, which are scheduled for strategic dates during high-traffic periods, will affect multiple airports, and essential services will continue at reduced levels. While the unions involved seek improved working conditions and wages, the strikes have the potential to create major inconveniences for passengers. Travelers are urged to plan accordingly by staying informed about flight statuses and considering alternative travel arrangements.
