A significant labor dispute has paralyzed a vast majority of Aldi supermarkets in the Brussels-Halle-Vilvoorde region, as employees launch a wave of strikes to protest potential changes to their working schedules. The unrest, which peaked on Saturday, May 2, 2026, saw more than 80% of Aldi stores in the administrative zone shut their doors, disrupting retail operations across the capital and its periphery according to reports from La DH.
The catalyst for the walkouts is a management proposal to enter negotiations regarding the possibility of Sunday openings. For the workforce, the prospect of working on Sundays represents a fundamental shift in their work-life balance and a threat to the only guaranteed day of rest for many staff members. The strike in Brussels and the surrounding areas is the latest escalation in a broader national trend of unrest within the discount giant’s Belgian operations.
The strike action in the Brussels-Halle-Vilvoorde region was supported by the Setca and CNE unions, with personnel in areas such as Anderlecht, Saint-Gilles, Uccle, Drogenbos, and Steenokkerzeel participating in the débrayage. Safouane Akremi, a union permanent for Setca BHV, confirmed that the workers are denouncing the announcement of negotiations around future Sunday openings as reported by RTL Info.
The Battle Over Sunday Openings in Belgium
The tension at Aldi is not an isolated incident but part of a shifting competitive landscape in the Belgian retail sector. Major chains such as Carrefour, Delhaize, and Okay already operate on Sundays, creating a commercial pressure on other discounters to adapt. Aldi management indicated that they wish to negotiate with unions to potentially open on Sundays to avoid a loss of revenue and to remain competitive against these rivals as noted by RetailDetail EU.
However, this strategic move has met with fierce resistance from the workforce. In Belgium, the “Sunday rest” is a deeply ingrained cultural and labor standard. For Aldi employees, the potential loss of Sunday as a free day is seen as an unacceptable concession. The strikes have been characterized as spontaneous, with workers setting up pickets to communicate their anger and demand that their current working conditions be preserved.
The scale of the disruption has fluctuated over the past few weeks. In late April, the unrest began with spontaneous strikes in about 20 stores in Flanders according to VRT NWS. By April 24, the movement had expanded nationwide, with approximately 60 stores closed across Belgium, including roughly 30 in Wallonia according to La Libre.
Impact on Consumers and Regional Operations
For residents of Brussels and the Halle-Vilvoorde periphery, the strike has caused significant inconvenience. The fact that eight out of ten stores in the region were closed on Saturday means thousands of shoppers were unable to access the discount retailer’s services. While some stores in other parts of Flanders and Wallonia remained operational, the concentration of closures in the capital region highlighted the strength of the union presence in the BHV zone.
The labor dispute underscores a growing friction between the “on-demand” expectations of modern consumers and the labor protections of retail workers. While management argues that Sunday openings are necessary to compete with the likes of Carrefour, unions argue that the human cost—specifically the loss of family time and mental recovery—outweighs the potential increase in profit.
Key Stakeholders and Their Positions
- Aldi Management: Seeking to negotiate Sunday openings to maintain market share and prevent revenue loss to competitors.
- Store Employees: Protesting the potential loss of their only guaranteed day off, leading to spontaneous walkouts and picket lines.
- Unions (Setca, CNE, ABVV): Supporting the workers’ right to maintain Sunday closures and pushing for a clear mandate from the personnel to establish a “plan of attack” in negotiations.
- Consumers: Facing sudden store closures and reduced availability of low-cost groceries in the Brussels region.
What Happens Next for Aldi Belgium?
The situation remains volatile. While some periods of “relative calm” were reported in late April after a brief wave of closures, the surge of strikes in the Brussels-Halle-Vilvoorde region in early May suggests that the underlying conflict remains unresolved. The unions have indicated that they will consult with personnel to obtain a clear mandate before proceeding further with management.
The outcome of these negotiations will likely serve as a bellwether for other retail chains in Belgium. If Aldi successfully implements Sunday openings without further labor collapse, it may embolden other discounters. Conversely, if the unions successfully block the move, it will reinforce the strength of the Sunday rest tradition in the Belgian labor market.
As of now, there is no confirmed date for a final agreement, but the intensity of the May 2nd strikes indicates that the workforce is prepared to maintain pressure on management to protect their weekends. We will continue to monitor official statements from the Setca and CNE unions regarding the next steps in the collective bargaining process.
