Hundreds of construction workers have staged protests at Novo Nordisk building sites in Denmark, demanding that the pharma giant force all subcontractors to sign recognised collective agreements and accept chain liability for working conditions across its projects.
The demonstrations have been rolling across Novo Nordisk construction sites since early this week. Around 100 plumbing and heating fitters sat down on the job Monday in Hillerød after their shop steward was sent home. By Thursday, reports put the number of protesters as high as 500 at related sites. The workers are not asking for more pay or shorter hours. They want the company to guarantee that every firm in the subcontracting chain operates under a Danish collective agreement.
Why This Matters for Foreign Workers
The dispute centres on two linked demands. First, that all contractors working on Novo Nordisk sites must be covered by a recognised overenskomst. Second, that Novo Nordisk itself must accept chain liability, meaning it takes responsibility for conditions all the way down the supply chain. According to the unions involved, the company has so far resisted both.
For expats working in construction or living near big Danish building sites, this is more than a labour spat. Denmark has no universal statutory minimum wage. Instead, pay, hours, overtime, and workplace rights flow from collective agreements negotiated by unions and employer groups. If your subcontractor is not covered, you may be earning less, working longer, or sleeping in substandard accommodation even while the headline employer is Novo Nordisk. That reality is what the protesters call social dumping.
What Sparked the Protests
The immediate trigger was the removal of a union representative from a Hillerød site. As reported by the union press, around 100 heating fitters stopped work Monday to demand his return. By Thursday morning, the protest had widened to include other trades and other Novo sites. Video footage from TV Kalundborg showed workers gathering outside company gates with union banners.
The scale suggests this is no longer a single-site grievance. It has become a test case for how Denmark’s largest private employer handles labour standards when it outsources construction work. Novo Nordisk responded to media questions but did not commit publicly to the workers’ core demands. The company has long been a national economic pillar, which means labour disputes here attract scrutiny that similar conflicts elsewhere might not.
Union Pressure and the Danish Model
Danish unions enforce standards through collective action, not court battles. That is the system. If a subcontractor underpays or mistreats workers, the union response is often a blockade or work stoppage rather than a lawsuit. The protests at Novo sites follow that pattern. Workers are using leverage, not lawyers.
I have watched this model work and fail over the years. When it works, it raises conditions quickly and forces companies to police their suppliers. When it fails, foreign workers can be caught in the middle, unsure of their rights and unclear about who is actually responsible for their contract. Chain liability is meant to close that gap by making the main employer answer for every link.
What Workers Should Do
If you are working on a Danish construction site tied to a major employer, check whether your direct employer is covered by a collective agreement. Ask if there is a tillidsmand or union contact on site. If you are sent home or reassigned after raising concerns, keep copies of payslips, shift schedules, and any written instructions.
The quickest route to help is usually the relevant union branch, often 3F for construction trades. Arbejdstilsynet handles workplace safety inspections, and Borger.dk and nyidanmark.dk offer official guidance on work permits and residence conditions. If your permit is tied to an employer, verify that your status is still valid if conditions change.
The Novo Nordisk dispute is still unfolding. But the pattern is clear. Danish unions are pushing the country’s most powerful company to own responsibility for every worker on its sites. For expats, the outcome will shape what collective agreements mean in practice when the employer is a subcontractor you have never heard of.
