You receive a job offer in Germany and the contract arrives. The language is formal. Terms like Probezeit and Befristung appear. Understanding what those clauses actually mean protects both sides from later surprises.

German employment law is protective and detailed. The written contract, the probation period, and any fixed-term arrangement each carry specific legal consequences. Here is a clear overview of the rules that matter most in everyday practice.

The Employment Contract Itself

German law expects the essential terms of employment to be set out clearly. Since the strengthening of the Nachweisgesetz, employers must provide written information on core conditions—pay, working time, notice periods, and related matters—quickly and in a form that meets statutory requirements. A full written employment contract remains the safest and most common practice.

Verbal agreements can create a valid employment relationship, yet they leave far more room for dispute. Both parties benefit from a signed document that records start date, salary, working hours, annual leave, notice periods, and any special arrangements such as overtime rules or non-compete clauses.

Probation Period (Probezeit)

A probation period of up to six months is standard and widely used. During this time the statutory notice period shortens to two weeks unless the contract or a collective agreement provides otherwise. Either side can end the relationship more easily than after the probation ends.

The probation period is not automatic. It must be agreed. In fixed-term contracts the length of any probation must remain proportionate to the overall duration and the nature of the work. Courts have held that a probation period covering the entire fixed term is usually disproportionate and therefore invalid.

Once the six-month mark passes, stronger dismissal protection under the Kündigungsschutzgesetz often applies (in businesses with more than ten employees). The end of probation is therefore a significant legal threshold.

Fixed-Term Contracts (Befristung)

Fixed-term employment is regulated by the Teilzeit- und Befristungsgesetz (TzBfG). Two main routes exist.

A fixed term with an objective reason (Sachgrund) is possible for various recognised grounds—temporary need, substitution of another employee, the nature of the work, or reasons related to the employee’s person. When a valid objective reason exists, successive fixed-term contracts can continue for longer periods.

A fixed term without objective reason (sachgrundlose Befristung) is more tightly limited. Under the rules applicable in 2026 the maximum duration is generally two years, and the contract may be extended at most three times within that period. New businesses and certain older employees who were previously unemployed enjoy longer possibilities. An important restriction is the “Anschlussverbot”: a new fixed-term contract without objective reason is usually blocked if the employee already worked for the same employer in the recent past.

The fixed-term agreement itself must normally be in writing to be effective. If the written form is missing, the contract is generally treated as open-ended.

Key Employee Rights That Apply from Day One

Even during probation and under a fixed-term contract, core protections remain in force. Minimum wage rules, working-time limits, holiday entitlement, and protection against discrimination apply. Maternity and parental rights are not suspended by a fixed term or probation. Social insurance contributions begin with the employment relationship.

After six months of continuous employment in a qualifying business, the Kündigungsschutzgesetz requires social justification for ordinary dismissals. Fixed-term contracts simply expire at the agreed end date without the need for dismissal, provided the fixed term is valid.

Practical Points for Employees and Employers

Employees should read the contract carefully before signing. Check the exact length of any probation, the notice periods, and whether the contract is open-ended or fixed-term. If it is fixed-term, note whether an objective reason is stated and whether the duration stays within legal limits.

Employers should ensure that fixed-term clauses meet the formal and substantive requirements of the TzBfG. An invalid fixed-term clause converts the relationship into an indefinite one, with all the accompanying dismissal protection. Probation periods in short fixed-term contracts need particular care so they remain proportionate.

Both sides benefit from clear documentation of any later changes—extensions, salary adjustments, or alterations to working time—preferably in written form.

Looking at Pending Discussions

Policy discussions in 2026 have included proposals to lengthen the maximum duration of fixed-term contracts without objective reason and to adjust formal requirements. Until any such changes are enacted and enter into force, the existing limits of the TzBfG continue to apply. Always verify the rules in force on the date the contract is concluded.

German employment contracts combine contractual freedom with strong statutory guardrails. A well-drafted agreement that respects the rules on probation and fixed-term employment reduces uncertainty for everyone involved. Take the time to understand the clauses that govern the first months and the possible end date of the relationship. Clear terms at the beginning prevent most disputes later.
