BRUSSELS — Belgium’s streets will once again become a battleground this Tuesday as the country prepares for its fifth national strike since the Arizona Coalition government took office, a protest movement that has grown into one of the largest labor mobilizations in decades. With unions and progressive groups vowing to maintain pressure on Prime Minister Bart De Wever, the question looms: Can mass demonstrations truly derail the legislative agenda of a government that has already weathered months of opposition?
The stakes are high. The Arizona Coalition—a center-right alliance led by De Wever’s New Flemish Alliance (N-VA)—has pushed through a sweeping law-programme (legislative package) that includes deep spending cuts, pension reforms, and labor market flexibilization. Critics, including the Federation of Belgian Trade Unions (FGTB) and the left-wing Workers’ Party of Belgium (PTB-PVDA), argue the measures disproportionately target workers, public services, and social protections. The government insists the reforms are necessary to stabilize Belgium’s finances amid global economic uncertainty.
Yet the protests suggest otherwise. On March 12, 2026, an estimated 100,000 people took to the streets in Brussels alone, marking a year of resistance against the coalition’s austerity plans. The demonstrations have forced the government to backtrack on some proposals, but key elements of the law-programme remain under debate. With Tuesday’s strike set to disrupt transport, education, and public services nationwide, the pressure is intensifying. “This is not just about one law,” said Sofie Merlaen, a spokesperson for the FGTB. “It’s about the future of our social model.”
Can street protests change the outcome of parliamentary votes in Belgium? The answer lies in the country’s unique political culture—where mass mobilization often shapes policy, but legislative majorities ultimately hold sway.
The Fifth Strike: A Movement Without Precedent
Belgium’s labor movement has a long history of militant action, but the current wave of strikes stands out for its scale, and persistence. Since the Arizona Coalition assumed power in late 2025, unions have organized four previous national strikes, each drawing tens of thousands of participants. The most recent, on March 12, saw demonstrations across Flanders, Wallonia, and Brussels, with estimates ranging from 80,000 to 120,000 protesters, according to police and union reports.
What makes this movement unusual is its breadth. Beyond traditional labor unions, it includes student groups, pensioners’ associations, and even environmental activists who oppose the government’s deregulation of industrial zones. The PTB-PVDA, led by Raquel Varela, has framed the resistance as a defense of Belgium’s welfare state, warning that the law-programme could erode decades of social progress.
Yet the protests face structural challenges. Belgium’s federal system means regional governments—Flanders, Wallonia, and Brussels—often have competing priorities. While Flanders, dominated by De Wever’s N-VA, may support austerity, Wallonia and Brussels, with stronger socialist and green parties, are more resistant. This regional divide complicates the unions’ ability to present a unified front.
What’s in the Controversial Law-Programme?
The Arizona Coalition’s law-programme is a 200-page document that touches nearly every aspect of Belgian life. Key provisions include:
- Pension reforms: Raising the retirement age from 65 to 67 and linking future increases to economic growth rather than inflation.
- Labor market changes: Expanding temporary contracts and reducing severance protections for certain industries.
- Public sector cuts: Freezing wages for civil servants and privatizing parts of healthcare and education.
- Tax adjustments: Lowering corporate taxes while increasing VAT on essential goods.
The government argues these measures are necessary to reduce Belgium’s public debt, which stood at €560 billion (55% of GDP) in 2025, according to the European Commission. Critics, however, warn the reforms will deepen inequality in a country where the Gini coefficient is already 24.9, one of the lowest in Europe.
Opposition parties, including the Socialist Party (PS) and Green Party, have vowed to block the law-programme in the Chamber of Representatives. Yet with the Arizona Coalition holding a slim majority, passage remains likely—unless the protests force a political realignment.
History Shows Protests Matter—but So Do Votes
Belgium has a long tradition of street power. In 1960–61, mass strikes helped secure independence from colonial rule. In the 1990s, protests against austerity contributed to the fall of the Christian Democratic government. More recently, the Yellow Vest movement in 2018–19 forced concessions on fuel taxes.
However, Belgium’s parliamentary system means laws ultimately pass—or fail—based on votes. The Arizona Coalition’s majority in the Chamber of Representatives (124 seats out of 150) gives it significant leverage. While strikes can delay or modify legislation, they rarely overturn it entirely. “The government can ignore protests if it has the numbers,” said Jean-Quentin Pirard, a political scientist at the Free University of Brussels (ULB).
Yet Notice exceptions. In 2020, protests against a controversial asylum reform bill led to its withdrawal after 150,000 people marched in Brussels. The current movement may not reach that scale, but it has already achieved tactical victories: the government delayed the pension reforms by six months and softened some labor market changes.
Stakeholders in the Battle Over Belgium’s Future
The law-programme’s passage—or defeat—will have far-reaching consequences:
- Workers: Unions warn of job insecurity, especially for temporary and gig workers. The FGTB estimates 300,000 jobs could be affected by labor market reforms.
- Pensioners: The retirement age hike would disproportionately impact women, who live longer on average, and low-income earners.
- Public sector employees: Teachers, nurses, and civil servants face wage freezes, while private contractors may see pay cuts.
- Students: Higher education funding cuts could lead to tuition increases, with the Federation of Student Unions predicting €500 annual hikes.
- Businesses: While corporate taxes drop, little businesses may struggle with higher VAT on goods like food and energy.
Meanwhile, the political landscape is shifting. The Socialist Party (PS) and Green Party have gained traction in recent polls, suggesting public discontent with the Arizona Coalition’s approach. If the strikes sustain momentum, they could erode the coalition’s majority, forcing negotiations—or a snap election.
Tuesday’s Strike and Beyond
Tuesday’s fifth national strike is expected to be the largest yet, with unions calling for a 24-hour shutdown of key sectors. Transport disruptions are likely, with SNCF-Belgium and De Lijn already warning of limited services. Schools and universities may close, and public administration could operate at reduced capacity.
The government has not indicated it will back down, but internal divisions are growing. Paul Van Tigchelt, a senior N-VA official, told Belgian media that “the protests have had an impact, but the law-programme is not negotiable in its entirety.” Meanwhile, opposition leaders are preparing for a parliamentary vote on the pension reforms as early as June 2026.
For now, the movement’s leaders are focusing on maintaining pressure. “We’re not just striking against a law,” said Raquel Varela of the PTB-PVDA. “We’re striking for a different Belgium—one where workers and the poor aren’t paying the price for the crisis.”
Key Takeaways

- The Arizona Coalition’s law-programme includes pension reforms, labor market changes, and public sector cuts, sparking widespread opposition.
- While protests have forced some concessions, Belgium’s parliamentary system means legislative outcomes depend on votes—not just street power.
- Stakeholders from workers to students stand to lose under the reforms, while businesses may see mixed benefits from tax changes.
- The next critical checkpoint is the June 2026 parliamentary vote on pension reforms, with opposition parties preparing to challenge the government’s majority.
