Temporary Work Contracts in Denmark: Key Clauses for Polish Construction Workers 2026

A temporary work contract in Denmark is not just a formality, for a Polish construction worker stepping onto a Danish site for the first time, it is the single most important document determining wages, working hours, safety obligations, and what happens if things go wrong. Yet many workers sign these contracts quickly, often in Polish, without fully understanding which clauses actually offer legal protection and which ones leave them exposed. This guide walks through the key provisions that matter most, step by step.

Step 1: Check Your Eligibility and Posting Status

Before examining any contract, a Polish worker needs to understand the legal framework under which they are being sent to Denmark. There are two fundamentally different situations: working directly for a Danish employer, or being posted by a Polish temporary work agency. The latter is governed by both Polish law, specifically the Kodeks Pracy (Polish Labour Code) and the Act on Employment of Temporary Workers, and Danish law, including the rules enforced by Arbejdstilsynet, the Danish Working Environment Authority.

If you are sent by a Polish agency, your employer on paper remains the Polish agency, but Danish rules on minimum wages, working time, and health and safety apply at the Danish construction site. This is the core principle of the EU Posted Workers Directive, transposed into Danish law. Understanding this distinction matters because it affects which authority you can complain to if a clause is violated. For a broader look at how Polish agencies operate legally in this space, the article on How to Register a Temporary Work Agency Sending Workers to Denmark 2026 provides useful context.

Step 2: Gather the Required Documents Before You Sign

A legitimate temporary work contract package should include several documents. The contract itself must state the name and address of both the Polish agency and the Danish user company, the nature and location of the work, the expected duration of the posting, and, critically, the applicable wage rate. Alongside the contract, you should receive a written statement of terms (known in Danish as an ansættelsesbevis), which Danish law requires to be issued within seven days of starting work.

Polish workers should also ensure their ZUS A1 certificate is in order before departure. This document, issued by the Polish Social Insurance Institution, confirms that social contributions continue to be paid in Poland during the posting period and prevents double taxation of social contributions. Without it, a worker may face complications with both Polish and Danish authorities. You can apply for the A1 form through the ZUS portal at zus.pl.

Step 3: Identify the Protective Clauses in the Contract

Not all contract clauses are equal. Some protect the worker; others protect the agency. Here are the provisions that carry the most practical weight for a Polish construction worker in Denmark.

Wage and Overtime Provisions

Denmark does not have a statutory national minimum wage set by legislation, but wages in the construction sector are regulated by collective agreements, most notably those negotiated under the umbrella of the Danish Confederation of Trade Unions. Any contract that fails to reference the applicable collective agreement, or that sets a rate significantly below the going rate for the trade, is a red flag. The contract should specify the hourly rate, the overtime multiplier, and when overtime kicks in.

Working Time and Rest Periods

Danish working time rules align with the EU Working Time Directive, which sets a maximum average of 48 working hours per week and guarantees minimum daily and weekly rest periods. If a contract contains a clause asking the worker to "voluntarily" waive the 48-hour limit without any corresponding benefit or clear opt-out process, that clause deserves scrutiny. Construction sites often run intensive schedules, and managing rotation fairly is a persistent challenge, something explored in depth in the article on Rotation Schedule Chaos: How Polish Agencies Regain Control in 2026.

Health, Safety, and Equipment

Under Danish law, Arbejdstilsynet holds both the Danish user company and, in some circumstances, the Polish sending agency responsible for ensuring safe working conditions. The contract should clearly state who is responsible for providing personal protective equipment, who covers the cost of mandatory safety training, and what procedure applies if a worker is injured. A clause that shifts all safety costs onto the worker, or that makes safety training a condition for receiving full pay, is not compliant with Danish working environment rules.

Accommodation and Travel Allowances

Many Polish workers in Denmark are provided accommodation by the agency. The contract must specify whether accommodation costs are deducted from wages and, if so, at what rate. Danish authorities have scrutinised cases where excessive accommodation deductions effectively reduce take-home pay below the collectively agreed rate. If accommodation is provided, the contract should describe the standard of housing. Vague language such as "suitable accommodation will be arranged" without further detail leaves the worker with little recourse.

Step 4: Submit the Contract for Review Before Signing

Polish workers have the right to consult their contract before signing. The Państwowa Inspekcja Pracy (PIP), Poland's National Labour Inspectorate, operates advice lines and regional offices where workers can have contracts reviewed at no cost. This step is particularly valuable for first-time postings. PIP can flag clauses that violate Polish labour law even when the work is performed abroad. More information is available at pip.gov.pl.

In Denmark, the relevant authority for questions about working conditions is Arbejdstilsynet, reachable through at.dk. Workers and agencies can both use this resource to clarify obligations before a posting begins, not only after a dispute arises.

Step 5: Know What to Do If a Clause Is Violated

If a worker discovers mid-posting that wages are being withheld, rest periods are not respected, or safety equipment is absent, the first step is to document everything in writing, emails, text messages, payslips, and photographs of the worksite. Verbal complaints are difficult to prove. A formal written complaint to the Danish user company, copied to the Polish agency, creates a paper trail that both PIP and Arbejdstilsynet can act on.

For wage disputes specifically, Danish trade unions have historically been active in recovering unpaid wages for posted workers, including those from Poland. Joining a relevant union before or shortly after arrival provides access to legal support that can be decisive in a dispute.

Common Mistakes to Avoid

One of the most frequent errors is signing a contract that is only available in Danish, without requesting a Polish translation or at minimum a written summary in Polish. An agency that refuses this request is itself a warning sign. Another common mistake is overlooking the termination clause: some contracts allow the agency to end the posting with very short notice and no compensation, leaving the worker stranded in Denmark without income or a return travel arrangement. Always check what the contract says about early termination, repatriation costs, and who pays if the Danish project is cancelled.

Finally, never assume that because a contract looks professional and is printed on headed paper, it complies with the law. Verification through PIP before departure and awareness of Arbejdstilsynet's role in Denmark are the two most reliable safeguards a Polish construction worker has when taking on temporary work under a Danish contract.
