Operational Context
Belgium experiences recurrent industrial actions across the public transport sector, with Brussels historically facing significant operational strain during metro, tram and bus strikes. STIB depot walkouts, whether coordinated or staggered, have repeatedly resulted in large-scale service suspensions, commuter overload and heavy congestion on arterial routes feeding the EU Quarter and central city zones. Past actions in March, May and November have shown predictable strike timing, often lasting 12 to 24 hours with occasional extensions when negotiations falter. Brussels’ reliance on multimodal public transport makes it vulnerable to rapid congestion when metro and tram lines stall; private car use surges, placing pressure on major corridors such as Avenue Louise, Boulevard Anspach and Rue de la Loi. While these events rarely produce major safety incidents, they have triggered isolated clashes around demonstrations and caused measurable business disruption, absenteeism and supply-chain delays across the Brussels-Capital Region.
Executive Summary
- Event Date: 12 December
- Location: Brussels, Belgium
- Risk Category: Civil Disturbance
- Severity Level: 3 / 5
- Confidence Score: 85 %
A full-day transport strike by CGSP affecting all STIB depots on 12 December will significantly reduce or suspend metro, tram and bus services. Severe commuter disruption, heavy congestion on main arteries and delays to business operations are anticipated.
Known Hotspots & Sensitive Zones
- High Impact Zones: Central pedestrianised belt around Boulevard Anspach, the EU institutions corridor along Rue de la Loi, Avenue Louise commercial areas and the Brussels-South (Midi/Zuid) station zone
- Medium Impact Zones: Airport feeder roads, Parc du Cinquantenaire, and secondary tram intersections.
- Low Impact Zones: Outer communes with greater road diversion options.
Brussels frequently experiences transport strikes during the winter period, contributing to seasonal congestion and labour mobilisation.
Impact on Transportation & Services
Major STIB routes are likely to be suspended or heavily curtailed, forcing reliance on SNCB rail and private road transport. Increased commuter pressure may produce delays at Brussels Airport due to overloaded bus and train connectors. Businesses in central Brussels will experience employee lateness, reduced footfall and delayed deliveries. Customer-service channels may spike in volume, while in-person appointments could be rescheduled or shifted to virtual formats.
Recommended Action
- Activate a strike-response plan by early morning, designating an incident lead and issuing mobility guidance to staff.
- Remote work should be mandated for non-essential personnel, while essential employees may use reimbursed taxis or contracted ride-share services.
- Secure sites, schedule enhanced security patrols and restrict deliveries to pre-cleared windows.
- Re-route inbound and outbound shipments through alternative corridors or secondary Belgian hubs.
- Publish real-time service updates, adjust customer commitments and provide escalation channels. Agencies that can support include the Brussels-Capital Region Police, STIB advisories, SNCB travel alerts and national emergency services.
Multi-Dimensional Impact
The strike may overlap with unrelated SNCB timetable changes and seasonal protests, compounding congestion at central stations and increasing the burden on emergency services. Logistics for planned municipal works may be delayed if contractor mobility is affected.
Emergency Contacts
- Brussels Police (Non-Emergency): 101

- SNCB Rail Information: 02/607 30 00
Situational Outlook
The most likely outcome is a one-day strike causing severe but time-bound disruption across public transport, with congestion easing by late evening once traffic volumes normalize. A moderate escalation may occur if pickets, demonstrations or stalled negotiations extend into the following day, prolonging route suspensions and forcing operational adjustments for businesses. A severe scenario, though less probable, involves a coordinated multi-day strike with large gatherings in central Brussels leading to additional road closures, safety concerns and prolonged supply-chain delays.
Strategic Takeaway
The CGSP strike highlights ongoing labour tensions within Brussels’ transport sector and underscores the city’s vulnerability to rapid mobility disruptions. Organizations should continue prioritizing flexible work models, resilient logistics routing and staff safety planning.
