Probation period explained: Rules, rights, and best practices by country

Probation periods are one of the most commonly used tools in hiring, yet they are governed very differently across jurisdictions. Rules on duration, extensions, notice periods, and termination rights often come from local employment laws rather than employer policy. A probation clause that is valid in one country may be unenforceable in another.

The risk becomes clear when employers apply the same employment contract across multiple markets. A US company hiring in the Netherlands, for example, cannot simply carry over its standard 90-day probation clause. Under Dutch law, probation periods are subject to strict limits, and non-compliant clauses can be rendered unenforceable. Similar restrictions exist across France, Germany, Mexico, and many other jurisdictions, making local compliance an essential part of international hiring.

The terms probation period and qualifying period are often used interchangeably, but they serve different purposes.

• A probation period is a defined period at the start of employment during which dismissal rules, notice requirements, or other employment protections may be modified or relaxed. Its maximum duration is typically set by legislation, collective bargaining agreements, or both.
• A qualifying period for unfair dismissal protection is the minimum length of service an employee must complete before gaining the statutory right to challenge a dismissal as unfair.

The UK illustrates the distinction clearly. A contractual probation period and statutory unfair dismissal rights operate independently. An employer may use a three-month probation period, while employment protections are determined by separate statutory rules that apply beyond the probationary period.

ILO Convention No. 158 allows member states to exclude probationary employees from dismissal-protection provisions, provided the probation period is of a “reasonable duration”. The Convention does not define a maximum length, leaving each jurisdiction to set its own limits. Across the countries covered in this article, statutory maxima range from 30 days in Mexico for most roles to 240 days in Portugal for certain senior positions.

Probation rules vary significantly across jurisdictions. The table below compares maximum probation periods, notice requirements, extension rules, and the legislation that governs them. Where collective bargaining agreements can modify the statutory position, this is noted separately.

Several recent developments have changed how probation periods are applied in Europe.

• In Italy, Law 203/2024 introduced a proportional approach for fixed-term contracts, linking probation length to the duration of the contract.
• In Germany, the Federal Labour Court’s October 2025 ruling confirmed that there is no fixed proportionality formula for probation in fixed-term contracts, with each case assessed according to the role, contract length, and surrounding circumstances.
• In France, a March 2026 Cour de cassation decision strengthened protections for pregnant employees by placing the burden on employers to demonstrate that a probationary dismissal was unrelated to pregnancy.

Probation periods may simplify certain employment procedures, but they do not remove an employee’s statutory rights. Employers still need to comply with local notice requirements, anti-discrimination laws, and employment obligations that apply from the first day of work.

Probation extensions are one of the easiest ways for employers to create compliance risk. While some countries allow extensions under specific conditions, others prohibit them entirely. In certain jurisdictions, an invalid extension can make the entire probation clause unenforceable.

The consequences vary significantly:

• Germany: Extensions are not permitted. The six-month maximum is absolute and cannot be extended by contract, mutual agreement, or collective bargaining agreement.
• France: One renewal is permitted, but only if the possibility is expressly stated in both the employment contract and the applicable collective bargaining agreement. Extensions that do not meet both conditions are void.
• The Netherlands: Exceeding the statutory maximum has one of the strictest outcomes in Europe. The probation period is not reduced to the legal limit; the entire clause becomes unenforceable.
• Poland: Employers may extend probation once where justified by the nature of the work, subject to statutory limits.
• Brazil: One extension is permitted provided the total probation period does not exceed 90 calendar days.
• UAE: Extensions are not permitted.

The practical takeaway is that probation periods should be treated as a local compliance requirement rather than a global HR policy. A probation framework that works in one jurisdiction may be invalid in another. Boundless helps employers apply local statutory limits and collective bargaining requirements when hiring internationally, reducing the risk of unenforceable probation clauses and related employment disputes.

A well-drafted probation clause does more than specify a duration. It creates a clear framework for evaluating performance, documenting decisions, and complying with local employment laws.

Key elements include:

• State the probation period clearly in writing: Many jurisdictions require the exact duration to be specified in the employment contract. References to a statutory or collective-agreement maximum may not be sufficient.
• Check proportionality for fixed-term contracts: Several countries impose additional rules on probation periods for fixed-term employees, linking the length of probation to the duration of the contract.
• Define performance expectations from the outset: Success criteria should be objective, measurable, and communicated before or on the employee’s first day.
• Schedule regular performance reviews: Structured check-ins throughout the probation period help employers document progress, provide feedback, and identify concerns early.
• Use a performance improvement plan before extending probation: Where extensions are permitted, employers should document performance concerns, expected improvements, and available support before making a decision.
• Review dismissal decisions for consistency: Employees in similar circumstances should be treated consistently to reduce discrimination and equal treatment risks.
• Train managers on probation requirements: Managers should understand local notice rules, documentation standards, and the employment rights that apply during probation.
• Follow local dismissal procedures where required: In some jurisdictions, probationary dismissals still require procedural safeguards, particularly once an employee reaches a certain length of service.

The strongest probation processes combine clear documentation, regular performance reviews, and local legal compliance. Together, they reduce the risk of disputes and provide a defensible basis for employment decisions.

When a company uses an Employer of Record (EOR) to hire in a foreign jurisdiction, the EOR becomes the legal employer in that country. Local probation rules apply in full, and the EOR cannot agree to a probation clause that exceeds the statutory maximum because the client company’s home country practices are different.

Collective bargaining agreement (CBA) obligations apply to the EOR as well. In France, Italy, and Spain, the EOR must follow the applicable sectoral or national CBA, including any rules governing probation duration, notice periods, and renewals. Social security and other statutory employment obligations begin from day one, including in the UAE, where employees must be registered with MOHRE from commencement.

For project-based roles where the individual operates with genuine independence, an Agent of Record (AOR) arrangement may sit outside the probation framework because probation applies to employees rather than independent contractors. However, misclassification risks remain significant in jurisdictions such as France, Spain, Brazil, and Australia, and AOR arrangements should be used only where the underlying relationship supports contractor status.

Boundless provides both EOR and AOR solutions across multiple jurisdictions, helping companies apply local employment rules from the outset. For employers hiring internationally, aligning probation clauses with local statutory requirements is often the simplest way to avoid unenforceable contract terms and related compliance risks.
