Assignment / Posting
Temporary work in another country, often involving formal notification, social security and employment-law questions.

In brief for employers
A posting is a temporary work assignment abroad in which employees work for their employer in another country. In contrast to workation, the posting is typically business-related and can trigger obligations regarding A1 certificate, posting notification, social security, labor law, tax and immigration.
Definition
A posting occurs when an employer temporarily sends employees to another country to work there. The deployment can take place at a group company, a customer, on a construction site, in a project or at another company location. Essentially, the person remains employed by the sending employer, but temporarily works outside the country of normal employment.
Assignment is not the same as a short business trip and also not the same as home office abroad. The distinction depends on the purpose, duration, activity, target country and organizational integration.
Why posting is relevant for employers
Assignments can trigger multiple areas of compliance at the same time. HR not only has to record travel and assignment data, but also check which reports, evidence and local requirements are necessary before the start of the assignment abroad. The connection to the A1 certificate and to social security agreement is particularly important.
Typical obligations and risks are:
- Proof of social security, especially A1 or comparable certificate
- Posting notification or posting notification in the destination country
- local minimum working conditions and labor protection regulations
- Immigration and work permit verification
- Tax issues such as 183-day rule, withholding tax or payroll
- Insurance, occupational safety and duty of care
- Documentation for controls, reviews and internal compliance
Important distinctions
| Term | Typical logic | distinction |
|---|---|---|
| posting | Employer sends person abroad for work | Often more formal, longer or more operational than a business trip. |
| business trip | Short-term business trip, such as meetings or conferences | May still require A1 or visa check, but is not automatic posting. |
| workation | Employee works temporarily from private residence | Privately motivated context; Compliance check is still necessary. |
| home office abroad | Work from a foreign place of residence or residence | Can be temporary or permanent and is not automatic posting. |

Frequently asked questions
Is every business trip a secondment?
No. A business trip can be very short and limited to meetings or conferences. A posting is usually a specific work assignment abroad. However, the distinction should always be checked.
Does a posting always require an A1 certificate?
For many European postings, an A1 certificate is central. Whether and how you apply for it depends on the state, the duration and the social security classification.
Is a workation a posting?
Mostly not. A workation is usually privately motivated. However, it can trigger similar checks, such as A1, tax, immigration or data protection.
