National strike in Belgium: what does it mean for you?
11-05-2026
Strikes and industrial action throw your daily routine off track. Fewer buses and trams, changed flights, delays on the road. We break down what this means for you as an employee or agency worker, and how to prepare.
National demonstration on 12 May
On Tuesday 12 May 2026, the three main Belgian trade unions (ACV, ABVV and ACLVB) are organising a national demonstration in Brussels against the federal government's policies. Disruption is expected across several sectors, especially public transport and aviation.
Disruption to public transport
On 12 May, expect disruption at De Lijn (Flanders' main bus and tram operator), with fewer services running across all of Flanders. The adjusted timetable goes live from Sunday evening, 10 May.
Aviation is affected too. Brussels Airlines is reducing its schedule, Brussels Airport expects disruption, and at Charleroi Airport all departing and arriving flights are cancelled.
Why is there a national strike?
The trade unions are taking action against reforms proposed by the federal government. They argue these reforms put pressure on purchasing power, wages, pensions and social protection.
What does it mean for you?
Your job: Working as an temporary worker through Accent? Whether you work that day depends on your sector and your employer. Not sure about your personal situation? Check with your employer and/or your contact at Accent beforehand.
Getting to work: Buses and trams face disruption. Plan an alternative in good time, like carpooling or working from home. If you arrive late or not at all because of announced disruption, you are in principle not entitled to pay for those hours.
Flights: Flying on 12 May? Check the latest updates from your airline and airport.
My bus or tram isn't running. What now?
An announced national strike affecting public transport is not an automatic valid excuse to stay home. Because the disruption is announced in advance, you are expected to take the necessary steps to get to work on time.
Check your route via the De Lijn website or app. Services that are not running simply won't appear in the route planner. Double-check your journey on the day itself too, as additional services may drop out unexpectedly.
What if there's a strike at my workplace?
If there is a strike in your company or department, as a temporary worker you are not allowed to work, even if you would like to. This applies even if you started your assignment before the strike began. During the strike, your agency is required to temporarily suspend your contract due to force majeure (unforeseen circumstances beyond anyone's control).
Good to know: are the blue-collar workers striking while you have a white-collar contract, or the other way around? Then you simply carry on working as normal.
How do you stay informed?
Check the news and updates from your employer, De Lijn, your airline or airport in good time. That way you avoid surprises and plan your day properly.
