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

In brief for employers
An assignment is a temporary work deployment abroad where employees work in another country for their employer. Unlike a workation, an assignment is usually business-driven and may trigger obligations around the A1 certificate, posting notifications, social security, employment law, tax and immigration.
Definition
An assignment occurs when an employer sends employees temporarily to another country to work there. The deployment may be to a group company, a customer, a construction site, a project location or another company site. In principle, the person remains employed by the sending employer but works outside the usual employment country for a period of time.
An assignment is not the same as a short business trip and not the same as home office abroad. The distinction depends on purpose, duration, activity, destination country and organisational setup.
Why assignments matter for employers
Assignments can trigger several compliance areas at once. HR needs to collect travel and deployment data and check which notifications, evidence and local requirements are needed before the assignment starts. The connection to the A1 certificate and social security agreements is especially important.
Typical duties and risks include:
- social security evidence, especially A1 or comparable certificates
- posting notification or local registration in the destination country
- local minimum employment conditions and worker protection rules
- immigration and work permit review
- tax questions such as the 183-day rule, withholding tax or payroll
- insurance, occupational safety and duty of care
- documentation for inspections, audits and internal compliance
Assignment, business trip, workation and remote work
| Term | Typical logic | Distinction |
|---|---|---|
| Assignment | Employer sends the person abroad for a work deployment | Often more formal, longer or more operational than a business trip. |
| Business trip | Short-term business travel, such as meetings or conferences | May still require A1 or visa checks, but is not automatically an assignment. |
| Workation | Employee works temporarily from a private stay location | Privately motivated context, but still needs compliance review. |
| Home office abroad | Work from a foreign residence or stay location | Can be temporary or long-term and is not automatically an assignment. |

Frequently asked questions
Is every business trip an assignment?
No. A short business trip is not automatically an assignment. The distinction depends on purpose, duration, activity and local rules in the destination country.
Does every assignment need an A1 certificate?
For many European assignments, an A1 certificate is an important social security document. The exact requirement depends on the countries and the setup.
Is a workation an assignment?
Usually not. A workation is normally privately motivated, while an assignment is employer-driven. Both still need compliance review.
