In Croatia, employment contracts must be concluded in writing. If the contract is not formally concluded in writing, the employer must issue a written confirmation (often referred to as a letter of engagement) before the employee begins work.

If neither is provided, the employment relationship can legally be presumed to be open-ended (indefinite) from day one.

Practical takeaway: Never allow an employee to start work without proper documentation in place. Administrative shortcuts can create long-term liability.

The Croatian Labour Act requires that employment contracts (or written confirmations) include specific information. These elements typically include:

• Full identification of employer and employee (including OIB – personal identification number)

• Place of work (or description of multiple/variable locations)

• Job title and type of work

• Date of conclusion and start date

• Whether the contract is open-ended or fixed-term

• If fixed-term, the expected duration or end date

• Annual leave entitlement or method of calculation

• Notice periods or method of determining them

• Gross salary structure (base pay and any supplements)

• Payment intervals

• Working hours (full-time or part-time)

• Probation period (if agreed)

• Information on training rights where applicable

Failure to include required elements can expose the employer to inspection penalties and disputes.

Fixed-term employment contracts are permitted—but they are regulated and cannot be used freely as rolling short-term arrangements.

Objective Reason Required

There must be an objective reason for concluding a fixed-term contract. It cannot simply be used as a trial substitute for open-ended employment.

Three-Year Rule

Successive fixed-term contracts generally may not exceed a total uninterrupted duration of three years, except in limited legally permitted situations (such as replacing a temporarily absent employee or certain project-based roles).

If fixed-term contracts are misused—or if an employee continues working after expiration without proper documentation—the relationship may legally convert into an open-ended contract.

Practical takeaway: Fixed-term contracts should be tracked carefully. They are compliance tools, not convenience tools.

Probation can be agreed between employer and employee, but it is subject to limits.

• The total probation period cannot exceed six months (including extensions due to absence).

• If employment is terminated during probation due to unsatisfactory performance, a minimum notice period (at least one week) applies.

Probation should be structured with clear evaluation criteria and documented performance reviews.

Croatia does not have “at-will” employment. Employers must generally have a justified reason for termination, and employees have the right to challenge dismissal before the courts.

Termination must follow legal procedure. This includes:

• Valid legal grounds

• Respecting notice periods

• Observing employee protections

• Proper written documentation

Notice periods depend on the employee’s length of service and are defined by law. They increase progressively with tenure.

Practical takeaway: Termination should never be improvised. A documented and legally structured process is essential.

Employees in Croatia are entitled to paid annual leave, with a statutory minimum aligned with EU standards (at least four weeks per year).

Important rules include:

• Employees cannot waive their right to annual leave.

• Agreements to replace leave with payment (outside termination scenarios) are invalid.

• Employers must communicate leave schedules in advance.

From an operational standpoint, workforce planning—especially during summer months—is critical, particularly in cities like Zagreb, Split, Dubrovnik, and Zadar where seasonal patterns affect staffing.

Confidentiality agreements are enforceable in Croatia, but their effectiveness depends on proper drafting and real-world implementation.

Croatia has specific legislation protecting trade secrets, aligned with EU law. To benefit from legal protection, businesses must demonstrate that the information:

1. Is not publicly known

2. Has commercial value

3. Is subject to reasonable protective measures

What a Strong NDA Should Include

• Clear definition of confidential information

• Exclusions (public knowledge, independently developed material, legally required disclosures)

• Rules for handling and storing confidential data

• Obligations upon termination (return or destruction of materials)

• Duration of confidentiality (often indefinite for trade secrets)

An NDA alone is not enough. Courts look at whether the company implemented actual security measures—access control, password protection, training, and structured offboarding procedures.

Post-employment non-compete clauses are permitted but are subject to strict conditions.

Key considerations include:

• The restriction must be proportionate.

• It must protect legitimate business interests.

• It must be limited in time.

• The employer must provide financial compensation during the restriction period.

Without proper compensation, a post-employment non-compete clause may not be enforceable.

For many businesses, a well-drafted confidentiality clause combined with non-solicitation language may provide adequate protection without the cost of a full non-compete.

When you hire employees in Croatia, you process personal data—identification numbers, payroll information, attendance records, and sometimes medical documentation.

Croatia applies the EU General Data Protection Regulation (GDPR) through national implementing legislation.

Best practice includes:

• Providing employees with a privacy notice

• Restricting HR data access

• Establishing document retention policies

• Implementing enhanced protection for sensitive data

Data protection compliance is not optional and should be built into onboarding procedures.

Before hiring, ensure you have:

• A written employment contract template compliant with the Croatian Labour Act

• A clear fixed-term strategy aligned with objective legal grounds

• A structured probation evaluation process

• A legally compliant termination framework

• A confidentiality and trade secret protection system

• A considered approach to non-compete compensation

• GDPR-compliant HR procedures

Croatia offers a stable, EU-aligned legal environment for employers. But that stability comes from structure and compliance. Employment contracts are not informal agreements—they are regulated legal instruments.

If you are hiring your first employee in Croatia—or reviewing existing contracts to ensure compliance—professional legal guidance can prevent costly disputes later.
