Portugal’s major airports are facing significant disruption again as ground-handling staff, employed by Menzies Aviation (formerly Groundforce), have launched a new wave of strike action. The strike calendar includes multiple weekends and holiday periods, beginning with September 3–9, 12–15, 19–22, and 26–28. Passengers are also advised to consider flexible travel plans and ensure they have insurance coverage for strike-related issues. Workers are calling for fairer wages, proper payment for night shifts, and the full respect of labor agreements. Union representatives maintain that they remain open to negotiations, while government authorities continue to monitor the situation closely.
