A strike (strejke) in Denmark is a collective work stoppage initiated by employees to apply pressure on an employer during negotiations. It is a fundamental and legal tool in the Danish labor market used to secure better wages, working hours, and conditions. When a labor conflict arises, workers deliberately withhold their labor until an agreement is reached.
In response to a strike, or as a preemptive measure, employers can initiate a lockout. A lockout is the employer’s equivalent of a strike. During a lockout, the employer physically or administratively prevents employees from coming to work, meaning the employees cannot earn their normal salary. Both strikes and lockouts are considered legal and natural parts of the collective bargaining process.
For foreign workers and expats, a Danish labor conflict can seem chaotic and intimidating. However, these conflicts are highly regulated and follow strict procedures. Strikes rarely happen out of nowhere. They are usually the final escalation after months of failed negotiations between worker representatives and employer associations.
The Danish Model: Why Strikes Happen
To understand strikes in Denmark, you must understand “The Danish Model” (Den Danske Model). Unlike many other countries, Denmark has very few labor laws dictating wages or working conditions. There is no legal minimum wage set by the Danish government. Instead, the labor market is regulated through collective agreements (overenskomst).
A collective agreement is a legally binding contract negotiated between trade unions in Denmark and employer associations. These agreements dictate everything from minimum pay rates and pension contributions to working hours and notice periods. Strikes are the primary weapon trade unions use to force employers to agree to fair terms when renewing these contracts.
Under the Danish Model, strikes are only legal when a collective agreement has expired and a new one is actively being negotiated. Once a collective agreement is signed and active, a “peace obligation” (fredspligt) goes into effect. During the peace obligation period, it is strictly illegal for workers to strike, and it is illegal for employers to initiate a lockout.
Danish Terminology: Strikes and Labor Conflicts
| Danish Term | English Translation | Brief Explanation |
|---|---|---|
| Strejke | Strike | Employees collectively stop working to pressure the employer during negotiations. |
| Lockout | Lockout | The employer prevents employees from working and stops paying their salary. |
| Overenskomst | Collective Agreement | The negotiated contract that dictates wages, working hours, and conditions. |
| Fredspligt | Peace Obligation | The period during an active agreement where strikes and lockouts are illegal. |
| Strejkekasse | Strike Fund | Money saved up by a trade union to financially support members during a conflict. |
| Konfliktunderstøttelse | Strike Pay | The tax-free or taxed financial support paid by the union to striking members. |
| Skruebrækker | Strike-breaker / Scab | A person who continues to work or takes over the work of striking employees. |
The terminology surrounding Danish labor conflicts is deeply embedded in the culture of the labor market. When a conflict is announced, you will frequently hear the terms “strejke” and “lockout” used together, as employers often respond to a targeted strike with a widespread lockout to force a quick resolution.
Understanding the concept of “fredspligt” is particularly crucial for foreign workers. If you participate in a work stoppage while a collective agreement is still active, you are breaking the peace obligation. This is considered an illegal strike, and you can be heavily fined by the Danish Labor Court (Arbejdsretten) for every hour you refuse to work.
The Difference Between A-kasse and Fagforening During a Strike
A common point of confusion for expats is the difference between an unemployment insurance fund and a trade union during a labor conflict. If you want to know what is an a-kasse, it is essentially a state-subsidized organization that pays out unemployment benefits if you are fired or laid off.
A trade union (fagforening), on the other hand, is a private organization that negotiates your salary, provides legal representation, and manages labor conflicts. During a strike or a lockout, your A-kasse becomes completely irrelevant. The A-kasse system is strictly neutral in labor conflicts and is prohibited by law from financing a strike.
If you are involved in a strike or a lockout, you cannot receive what is dagpenge (standard unemployment benefits). The state will not pay you while you are in conflict with your employer. Instead, your financial survival depends entirely on your trade union. The union will pay you “strike pay” from their private strike fund, provided you are a paying member.
How a Strike Works in Practice
A legal strike in Denmark cannot happen overnight. The rules require trade unions to issue formal warnings to the employers well in advance. Typically, a union must send a first warning (første varsel) at least 14 days before the intended strike. A second warning (andet varsel) must usually follow seven days before the strike begins.
These warning periods are designed to give both parties a final chance to reach an agreement. During this time, the Official Conciliator (Forligsmanden) usually steps in. The Conciliator is a neutral, state-appointed mediator whose job is to help the union and the employer find a compromise and avoid a conflict that could damage the Danish economy.
If the Conciliator believes an agreement is close, they have the legal authority to postpone the strike. They can delay the conflict for up to 14 days, and in some cases, an additional 14 days. If the mediation fails entirely, the Conciliator releases the parties, and the strike or lockout officially begins on the scheduled date.
What Happens to Your Salary and Benefits?
When you are on strike or locked out, your employment contract is temporarily suspended. You do not go to work, and your employer stops paying your salary immediately. You also stop earning standard employee benefits, such as employer-paid pension contributions and paid time off.
Instead of a salary, union members receive strike pay (konfliktunderstøttelse) from their trade union. The amount varies depending on the specific union, but it is generally designed to closely match your normal take-home pay. Some unions pay a flat daily rate, while others calculate a percentage of your usual salary.
Labor conflicts also impact your feriepenge (holiday allowance). Feriepenge is normally calculated as 12.5% of your qualifying salary, saved up to be used during your mandatory five weeks of vacation. Because you are not receiving a salary from your employer during a strike, you do not accrue holiday allowance for the days you are in conflict.
Other standard deductions are also affected. In Denmark, all working income is subject to AM-bidrag (labor market contribution), which is an 8% tax deducted before standard income tax. Strike pay is often exempt from AM-bidrag because it is classified as financial support rather than traditional salary, though standard income tax still applies.
Rules for Non-Union Members and Expats
The most significant risk for foreign workers in Denmark is facing a labor conflict without being a member of a trade union. Many expats choose to only join an A-kasse to secure unemployment benefits, skipping the trade union to save money on monthly membership fees. During a strike or lockout, this decision can have severe financial consequences.
If your workplace is selected for a legal strike by a trade union, but you are not a member of that union, you are generally expected to continue working if possible. However, if the employer initiates a lockout, or if the strike makes it impossible for you to perform your duties, the employer will send you home without pay.
Because you are not a union member, you will not receive strike pay from the union’s strike fund. Because you are involved in a workplace conflict, your A-kasse is legally forbidden from paying you unemployment benefits. You will simply be left with zero income for the entire duration of the conflict, which can last for weeks or even months.
Lockouts: When the Employer Strikes Back
A lockout is the employer’s most powerful tool in a labor conflict. When a trade union announces a strike, they often target specific, critical departments to cause maximum disruption while spending as little money from their strike fund as possible. Employers counter this by declaring a lockout.
During a lockout, the employer shuts out a massive portion of the workforce, regardless of whether those specific workers were planning to strike. The goal is to drain the trade union’s strike fund rapidly. If the union has to pay strike pay to 50,000 locked-out members instead of 5,000 striking members, their financial reserves will run out much faster, forcing them back to the negotiating table.
For the individual employee, a lockout feels exactly like a strike. You are not allowed to enter the workplace, you do not receive your salary, and you must rely on your trade union for financial support. Lockouts are completely legal as long as they follow the same warning procedures and occur outside the peace obligation period.
Illegal Strikes (Overenskomststridig Strejke)
Not all strikes in Denmark follow the rules. Sometimes, workers become so frustrated with local management, working conditions, or sudden layoffs that they walk off the job while a collective agreement is still active. This is known as an illegal strike or a wildcat strike (overenskomststridig arbejdsnedlæggelse).
Because an active collective agreement guarantees a peace obligation, participating in an illegal strike is a breach of contract. The trade union cannot legally support the strike, and they cannot pay strike pay to the participating workers. The union is actually legally obligated to order their members back to work immediately.
If the workers refuse to return to work, the employer can take the case to the Danish Labor Court. The court will almost always rule the strike illegal and issue a fine (bod) to the participating employees. This fine is typically calculated per hour of illegal strike action and is deducted directly from the workers’ future wages.
Impact on Sickness Benefits and Salaried Employees
If you become sick during a labor conflict, the rules can be complicated. Normally, if you fall ill, you are entitled to your salary or sygedagpenge (sickness benefits paid by the municipality). However, if a strike or lockout begins while you are already on sick leave, your right to employer-paid sick pay usually stops, and you transition to union strike pay or municipal benefits depending on the specific circumstances.
If you fall ill after a strike or lockout has already started, you are generally not entitled to sickness benefits from the municipality. You are considered part of the labor conflict, and you must continue to receive strike pay from your union until the conflict ends.
Many expats work under the Funktionærloven (The Salaried Employees Act), which provides strong legal protections regarding notice periods, severance pay, and illness for white-collar workers. However, during a legal labor conflict, the protections of Funktionærloven regarding salary and notice periods are temporarily suspended. The conflict overrides standard employment law until a new collective agreement is reached.
Concrete Examples of Labor Conflicts
To illustrate how strikes work in Denmark, consider a factory worker named Lars. Lars’s trade union is negotiating a new collective agreement with the factory owners. Negotiations break down over wage increases. The union issues the required 14-day and 7-day warnings and calls 500 factory workers out on strike. Lars stops working, his salary stops, and his union pays him strike pay. This is a legal, structured strike.
Now consider an IT worker named Maria. Maria and her team are upset because management suddenly canceled their remote work privileges. Even though their collective agreement is active and valid for another year, the team decides to log off and refuse to work until the privileges are restored. This is an illegal strike. Maria will not get strike pay, and she will likely be fined by the Labor Court for breaking the peace obligation.
Finally, consider an expat named John. John works at the same factory as Lars but chose not to join the trade union. When the union strikes, the factory owner decides to lock out the entire production floor. John is locked out. He gets no salary from the employer, no strike pay from the union, and no unemployment benefits from his A-kasse. John must survive on his own savings until the conflict ends.
Common Misconceptions for Foreign Workers
Many foreign workers assume that the Danish government will quickly step in to stop a strike if it disrupts public services or the economy. This is a misconception. The Danish Model relies on the government staying out of labor market disputes. The government will only intervene as an absolute last resort, usually by passing a special law to end the conflict if it threatens vital national interests or public health.
Another major misconception is that you can simply continue working if your colleagues go on strike. If your specific role is covered by the strike warning, continuing to work makes you a “skruebrækker” (strike-breaker or scab). This is highly stigmatized in Denmark. Trade unions will often exclude strike-breakers from membership, and it can permanently damage your relationship with your Danish colleagues.
Lastly, expats often believe that their employment contract protects them from lockouts. They assume that because their contract states they must be paid a monthly salary, the employer cannot legally withhold it. In Denmark, a legal labor conflict temporarily suspends the individual employment contract. The collective right to strike and lockout supersedes your individual contract until the conflict is resolved.
