What Is Employee Leasing?

Employee leasing (Arbeitnehmerüberlassung) is a triangular employment relationship involving three parties: the worker, the staffing agency (Verleiher), and the client company (Entleiher). The worker has an employment contract with the staffing agency, which then places them with client companies for defined periods.

The staffing agency remains the legal employer — responsible for salary, social security contributions, and employment law compliance. The client company directs the day-to-day work. To act as a staffing agency (Verleiher) within the scope of a commercial activity, permission from the Federal Employment Agency (Bundesagentur für Arbeit) is required.

This structure is regulated in Germany by the Arbeitnehmerüberlassungsgesetz (AÜG), which sets out rules on maximum placement duration, equal pay, and licensing requirements for agencies. A temporary worker may normally work for a client company for a maximum of 18 months, provided the work is not interrupted for more than three months during this period. Collective bargaining agreements may extend this to 24 months. Since April 2017, if a temporary worker has been placed with the same client for more than 18 months, the client is required to take them on as a permanent employee — or have them withdrawn by the agency.

When Do You Use Employee Leasing?

Employee leasing is most commonly used in the following situations:

Short-Term Capacity Needs

When a project demands more people than are currently employed, leased workers provide fast, compliant relief. The engagement can be ended once the demand subsides.

Absence Cover

Parental leave, long-term illness, or unexpected resignations can leave critical gaps. Employee leasing allows companies to fill these gaps quickly without committing to a permanent hire.

Seasonal or Project Peaks

Industries with variable demand — including IT project delivery — use employee leasing to match headcount to workload without permanent overstaffing.

Avoiding Short-Time Work

Rather than reducing existing employees to short-time working arrangements during fluctuating order volumes, companies can rely on temporary workers who can simply be returned to the agency once the need subsides — keeping the core workforce stable.

Trial Before Hire

Some companies use leasing as a pathway to permanent employment — testing a candidate in their environment before making a permanent offer.

Advantages of Employee Leasing

For the client company (Entleiher):

Speed

Leased workers can typically be placed much faster than permanent hires. For urgent vacancies or time-critical projects, this is a significant advantage.

Flexibility

Placements have a defined end date. Companies can scale their workforce up or down without the legal and financial complexity of redundancies.

Reduced Administrative Burden

The staffing agency handles payroll, social security contributions, and employment law compliance. Client companies benefit from the workforce without the associated HR administration.

Access to Pre-Screened Talent

Reputable staffing agencies maintain pools of candidates who have already been assessed for skills and reliability. This reduces the risk of unsuitable placements.

For the temporary worker:

Varied Fields of Activity

Temporary workers can get to know new areas of their profession across different client companies. This prevents monotony and ensures regular learning and development.

Crisis-Proof Employment

Temporary workers are paid by the staffing agency regardless of whether they are currently placed with a client or waiting for the next assignment. This provides a degree of income stability compared to being employed directly by a company whose order situation may collapse.

Easy Career Entry

Despite widespread talk of a skills shortage, career starters often find it difficult to secure their first role. Many companies require several years of experience for their vacancies. Temporary employment offers a practical route to gaining that initial experience and establishing a track record for a permanent position.

Disadvantages to consider:

Unknown Personality (for the client)

When selecting workers, the client company must rely on the staffing agency's assessment of candidate skills and suitability. There is less opportunity for a direct evaluation beforehand.

Team Integration (for the client)

Temporary workers are new to the team and need time to find their footing. Existing employees must repeatedly adjust to new colleagues and reorganise how they work together. It is the client's responsibility to foster harmonious structures and prevent friction between permanent staff and temporary workers.

Lack of Planning Security (for the worker)

While a temporary worker will usually spend at least several weeks at one company, they may have to change companies at regular intervals. Adapting to new colleagues and processes requires a high degree of flexibility.

Gaps Between Assignments (for the worker)

When a placement ends, there may not be an immediate follow-on project. During this waiting period, the temporary worker continues to be paid by the agency. However, if no further requests materialise in the foreseeable future, they will be released and must seek new work independently.

Are There Alternatives to Employee Leasing?

Yes. The main alternative for IT companies is engaging freelancers directly through a platform like ElevateX. Freelancers are self-employed, which means there is no employment relationship and different rules apply.

The key consideration is the nature of the work and the working relationship:

If the worker will be fully integrated into the client’s operations — following instructions, working set hours, using client equipment — then employee leasing (via a licensed agency) is the appropriate model. Direct freelance engagement in these circumstances risks being reclassified as Scheinselbstständigkeit.

If the worker will operate independently, across multiple clients, with their own tools and judgment — a genuine freelance engagement is the right approach and typically more cost-effective.

ElevateX helps companies navigate this distinction and structure engagements correctly from the outset.

FAQs

What is employee leasing (Arbeitnehmerüberlassung)?

Employee leasing is a staffing model where a licensed agency (the Verleiher) places workers with client companies (the Entleiher) for a defined period. The agency remains the legal employer while the client directs the work. It is regulated in Germany by the AÜG.

What is the difference between employee leasing and hiring a freelancer?

In employee leasing, the worker is an employee of the staffing agency — with all associated employment rights and employer obligations. A freelancer is self-employed, works independently, and the client is not responsible for their social security. The right model depends on how the work will actually be structured.

Does ElevateX offer employee leasing?

ElevateX primarily facilitates direct freelance engagements with self-employed IT specialists. For client situations that genuinely require the employee leasing model, we advise on the appropriate structure and can connect you with licensed Arbeitnehmerüberlassung providers.
