What’s a posted worker

Posted Workers

The term “Posted workers” (or at is known in Polish „pracownik delegowany”) is defined in the European Parliament and Council Directive 96/71/EC, and is governed by the Directive itself as well as by the member State’s national laws.

Posted worker is a person officially employed by a company registered in an EU member state (e.g. Poland), who’s temporarily posted to a different EU member country, for instance:

  • Germany
  • The Netherlands
  • Baltic States etc.

Companies officially registered in Poland (such as Sp. z o.o.) may officially post their employees to another member state.

A1 Certificate

A1 Certificate or A1 Form (known in Polish as zaświadczenie A1) is a legal document issued by a local Social Security Institution in an EU member state (in Poland that is ZUS), confirming that the employee is insured in the country issuing the certificate, and the social security contributions are paid.

Each worker that will be posted to a different EU country must have a valid A1 Certificate issued by the Polish authorities — ZUS (Zakład Ubezpieczeń Społecznych).

The A1 forms are issued on demand and can be obtained at any local ZUS branch in paper or in its digital format through the ZUS PUE portal. As with most Polish procedures the Polish national identification number (PESEL) must be obtained beforehand.

Posting your employee to a different EU state

Once the work permit (either „zezwolenie na pracę” or „oświadczenie” if applicable) has been registered, and the A1 Certificate has been successfully obtained, the employee can be legally posted abroad.

When crossing the border, the employee must carry and present on request, all registered documents that confirm the lawfulness of their employment (and stay) in the country of destination.

Once the validity of his permits has expired, the employee will be required to leave the country where he has been posted, otherwise, it will be a violation of the local law.

Remember: any employee working abroad is subject to local laws.

The incorporation procedure here in Poland is not as easy as one could expect, so the flexibility & professional support was of utmost importance for us. Everything was done very quickly, including opening a business bank account. We have been able to focus on our business while MF has taken care of our needs.

We had been a business incubator member for a while before we decided to open our own company, so we can work with European Clients. All the procedures went smoothly and without any problems whatsoever. Moja Firma continues to handle our accounting and helping us obtain residence permits for our employees.
