For companies and specialists working in regulated sectors such as energy and telecommunications, it is primarily about one thing: legal certainty.
Many projects today are delivered with external specialists. But how those professionals are engaged can be critical – for compliance, project stability, and long-term collaboration.
Why the Topic Is Becoming More Important
In recent years, scrutiny around false self-employment and labour leasing has increased significantly. Authorities are checking more closely, companies are becoming more cautious, and specialists themselves want to know that their engagement is structured correctly from a legal perspective.
Especially in large infrastructure projects, network rollouts, or energy programmes, teams often work together for months or even years. If the contractual structure is not appropriate, problems can arise later.
This is why it is important to clarify early on: is a freelance model really suitable – or is an AÜG structure the safer option?
When a Freelance Model Makes Sense
Freelance collaboration can work well when certain conditions are met.
Typical characteristics include:
-
A clearly defined project deliverable
-
A high degree of independence in the way the work is performed
-
No direct integration into internal teams
-
Use of the freelancer’s own equipment and working structures
In these situations, freelancers usually work independently and on a project basis. Responsibility for organisation and the way the work is carried out lies largely with them.
When these conditions are in place, a freelance model can be both efficient and flexible.
Where Risks Can Arise
Problems often occur where freelancers effectively work like internal employees.
For example, when they:
-
are fully integrated into a team
-
receive fixed working hours or direct instructions
-
work in the same project over long periods
-
are treated organisationally like employees
In these situations, there is a risk of false self-employment being suspected. The consequences can range from back payments of social security contributions to legal implications for the company.
This is why many companies now assess more carefully whether a freelance model truly fits the project structure.
When AÜG Is the Better Solution
Employee leasing under the German AÜG (Arbeitnehmerüberlassungsgesetz) can often provide a clear and legally secure alternative.
Under this model, external specialists are officially employed by a licensed provider and assigned to work on a project with the client.
This means:
-
A legally secure employment structure
-
Clear labour law framework
-
Integration into teams without the risk of false self-employment
-
Transparent contract and payroll structures
Particularly for long-term infrastructure projects or where close team collaboration is required, many companies therefore choose the AÜG model deliberately.
Why Many Specialists Now Appreciate AÜG
AÜG also offers advantages for specialists themselves.
Many project professionals value:
-
Legal security
-
Stable contractual structures
-
Predictable payment
-
Clear points of contact throughout the project
In a regulated market like Germany, this ultimately means one thing: less uncertainty and greater focus on the work itself.
The Right Structure Depends on the Project
There is no one-size-fits-all solution. Some projects are perfectly suited to a freelance model, while others require an AÜG structure.
The key is making the right decision early – before the project begins.
When engagement models are structured properly from the start, many risks can be avoided later.
