Belgium woke up on Saturday, 23 May 2026, to its fourth nationwide strike of the year – and the largest so far. From the pre-dawn hours, picket lines formed at Brussels Airport, Charleroi Airport, the Port of Antwerp-Bruges and scores of bus, tram and metro depots. By 06:00 the impact was clear: every scheduled departure from Brussels Airport had been cancelled, half of incoming services were scrapped and Charleroi closed altogether for the day.

For passengers suddenly rerouted through neighbouring countries or facing unexpected stopovers, VisaHQ can take at least one headache off the table. Through its Belgium portal (https://www.visahq.com/belgium/), travellers can instantly check transit-visa requirements, complete digital applications and arrange courier collection of passports, ensuring documentation keeps pace even when strike disruption forces last-minute itinerary changes.
Eurostar dropped one in six of its high-speed trains between Brussels and Paris, while Dutch airports in Rotterdam and Maastricht stepped in to operate diverted TUI and Wizz Air services. A ripple effect spread to other modes of transport. STIB-MIVB managed to run only one of Brussels’ four metro lines and a skeleton network of 13 bus and tram routes. In Wallonia, TEC reported that more than 50 routes were out of action, and no trams left the brand-new Bressoux depot in Liège. Inland shipping came to a standstill when the Common Nautical Authority halted vessel traffic on the Western Scheldt, forcing 40 ships to wait outside Antwerp. Port operators warned it would take up to two weeks to clear the backlog once normal operations resume. The walk-out was organised by Belgium’s three largest trade-union federations to protest federal budget cuts and labour-market reforms they say threaten purchasing power and workplace safety. Demonstrations drew an estimated 4,000 marchers through central Brussels, where union members placed a symbolic coffin outside the ruling N-VA party headquarters. Police maintained a heavy presence but reported no major incidents. For businesses, the industrial action amounts to an unplanned stress-test of mobility contingency plans. Multinationals with Belgian hubs activated remote-work protocols, shifted air cargo to neighbouring airports and rerouted expatriate arrivals via Amsterdam and Paris. Global mobility managers scrambled to rebook travellers and secure hotel rooms in the Netherlands and northern France. HR teams were also reminded that “force majeure” rules under Belgian law allow employees to claim paid leave when strikes make it impossible to reach the workplace. Although the strike is scheduled to end at 04:00 on Sunday, airport authorities predict continued congestion on 24 May, with Brussels Airport expecting 8,000 extra passengers as airlines clear the backlog. Mobility advisers recommend travellers allow at least three hours for check-in, monitor live updates and consider rail or road alternatives where feasible. Longer term, employers should review crisis-response playbooks and expand cross-border transport options to safeguard critical assignments in an environment of recurrent industrial unrest.
