If you employ people in Slovenia — or are scoping a Ljubljana office as part of an EU expansion — annual leave is one of the first compliance items your HR setup needs to handle correctly. The Slovenian Employment Relations Act (Zakon o delovnih razmerjih, commonly abbreviated as ZDR-1) sets a clear statutory floor for paid annual leave, but layers in extra entitlements driven by collective agreements that international employers routinely overlook.

This guide walks through what the ZDR-1 actually requires in 2026 — the four-week minimum, the 20-working-day baseline for a five-day worker, first-year pro-rata accrual, employer pay obligations during letni dopust, and the pitfalls that catch foreign employers most often. Every fact below is sourced from the Employment Relations Act and Slovenian government guidance.

Key Takeaways

Statutory annual leave is a minimum of 4 weeks per calendar year, equating to 20 working days for a standard five-day worker.
Collective agreements may layer additional days on top of the statutory floor for specific employee categories.
First-year employees accrue leave on a pro-rata basis, with one twelfth of the annual entitlement earned per completed month worked.
Employers must pay average earnings during annual leave — employees must not be financially worse off for taking statutory time off.
Untaken accrued leave must be paid out in cash when employment ends, and this right cannot be waived in the contract.

The Statutory Entitlement Under the ZDR-1

The Employment Relations Act sets a single, clean statutory floor. Every employee on a Slovenian employment contract is entitled to paid annual leave — known as letni dopust — at the following minimum:

At least four weeks of paid annual leave per calendar year.
For a standard five-day worker, this resolves to 20 working days per year.
For employees working a different weekly schedule, the four-week minimum is calculated against their actual working pattern.

The ZDR-1 frames the entitlement in weeks, not days. This is a deliberate choice and matters for part-time and compressed-schedule workers: a four-day worker on a four-day week is still entitled to four weeks of leave, which translates into 16 working days, not 20. Treating the entitlement as a fixed 20-day budget regardless of schedule is one of the most common mistakes foreign HRIS configurations make.

Additional Leave from Collective Agreements

The four-week minimum is the floor, not the ceiling. Slovenian collective agreements (kolektivne pogodbe) frequently add additional days on top of the statutory entitlement. Common drivers for additional days include:

Employees working under hazardous or arduous conditions.
Parents of minor children or dependants.
Employees with a disability.
Workers above certain age thresholds or with longer length of service.

The exact additions depend on the collective agreement that applies to the employer’s sector or company. Before publishing your leave policy, identify the applicable kolektivna pogodba and read the annual leave clauses — assuming the four-week ZDR-1 floor is sufficient is a frequent compliance gap.

Eligibility: Who Is Entitled to Annual Leave

Under the ZDR-1, all employees on a contract of employment are entitled to annual leave. Eligibility is universal — there is no minimum service threshold before leave begins to accrue. The mechanics differ slightly between the first year and every subsequent year.

First Year of Employment

In an employee’s first calendar year of employment, leave accrues on a monthly pro-rata basis. The employee earns one twelfth of the annual entitlement for each completed month worked. They do not receive the full four-week budget on day one — they accrue toward it over the months remaining in the calendar year.

For a five-day worker on the statutory minimum, this works out to roughly 1.67 working days of leave earned per completed month, rounded under the standard rule.

From the Second Calendar Year Onwards

From 1 January of each subsequent year, the full annual entitlement is granted at the start of the year. The employee does not have to wait to accrue it month by month — the budget is available to schedule from day one of the new year, subject to normal scheduling and approval.

Part-Time and Atypical Schedules

Part-time employees are entitled to four weeks of leave measured against their actual working pattern. A worker on a three-day week is entitled to four weeks of leave (12 working days for that schedule). The principle is that statutory leave is expressed in weeks and applied to whatever pattern the employee normally works.

Employer Obligations Under the ZDR-1

The Employment Relations Act puts several non-negotiable duties on the employer. Treat the following as a compliance checklist for any Slovenian payroll and leave setup.

1. Grant the Statutory Minimum

You must grant at least four weeks of paid annual leave per calendar year — 20 working days for a five-day worker, scaled to schedule for other patterns. Contracts that purport to offer less are void to the extent of the shortfall, and the statutory floor applies regardless.

2. Pay Average Earnings During Leave

The ZDR-1 requires the employee to be paid their average earnings during annual leave. Holiday pay is not a stripped-back base wage — it includes the regular pay components the employee would normally receive for performing their role. The employee must not be financially worse off because they exercised their statutory leave rights.

3. Allow the Employee to Take Leave Within the Calendar Year

Employers are required to allow annual leave to be taken within the calendar year in which it is granted. Refusing leave routinely or scheduling around it so the employee runs out of time to use it is a breach of the Act. In specific circumstances — most commonly long-term illness — unused leave may be carried over into the next year, but carry-over is the exception, not the operating model.

4. Pay Out Untaken Leave on Termination

When an employee leaves, untaken accrued annual leave must be paid out in cash. This is a statutory right and cannot be waived or negotiated away in the employment contract or a settlement agreement. Calculate the payout against the same average-earnings basis used for paid leave.

5. Apply the Collective Agreement Correctly

If a collective agreement covers the sector or the company, additional leave days set by that agreement are part of the legal entitlement, not a goodwill gesture. Audit the applicable kolektivna pogodba annually to make sure your policy keeps up with any changes negotiated by the social partners.

6. Maintain Accurate Records

Slovenian labour inspectors can request leave records during an audit. Keep auditable records of leave granted, taken, carried over, and paid out per employee. Missing or unreliable records typically lead to default findings against the employer.

Common Pitfalls for International Employers

If your team has only operated under UK, German, or US leave regimes before, the Slovenian framework will catch you off guard in predictable ways. Watch for these.

Pitfall 1: Treating the Four-Week Minimum as the Whole Story

The ZDR-1 sets a floor, not a ceiling. Slovenian collective agreements regularly add days for parents, older workers, disability, and hazardous work. Building your policy as a flat 20-day allowance for everyone will under-pay employees whose collective agreement provides more — and create back-pay exposure when discovered.

Pitfall 2: Hard-Coding 20 Days Regardless of Schedule

The entitlement is expressed in weeks, not days. A four-day-week employee is entitled to four weeks of leave (16 working days), not 20. Equally, a six-day worker would be entitled to more than 20 working days. Configure your HRIS to scale to the actual working pattern.

Pitfall 3: Not Paying Average Earnings During Leave

Holiday pay must reflect the employee’s average earnings for the role, not a stripped-back base wage. Excluding regular allowances or performance components routinely paid for ordinary work is a common payroll error and a clear breach of the Act.

Pitfall 4: Forgetting to Pay Out Unused Leave on Termination

This is mandatory under the ZDR-1 and cannot be waived. Trying to settle it for nothing in a separation agreement is unenforceable to the extent of the statutory entitlement. Build the cash-out into your termination payroll workflow by default.

Pitfall 5: Routine Carry-Over

Carry-over is permitted in narrow circumstances — most commonly when illness or other justified reasons prevented leave being taken. Treating carry-over as a normal operating practice signals to inspectors that the employer is not scheduling leave properly and routinely produces compliance findings.

Frequently Asked Questions

How many days of annual leave am I entitled to in Slovenia?

Annual leave is a minimum of four weeks per calendar year under the Employment Relations Act (ZDR-1). For a standard five-day worker this resolves to 20 working days. Collective agreements may add additional days on top of the statutory minimum.

What is letni dopust?

Letni dopust is the Slovenian term for paid annual leave. It is the statutory four-week minimum (or higher if a collective agreement applies) granted to every employee per calendar year under Article-level provisions of the ZDR-1.

When am I entitled to my full annual leave in Slovenia?

In the first calendar year of employment, leave accrues on a monthly pro-rata basis at one twelfth of the annual entitlement per completed month. From the second calendar year onwards, the full entitlement is granted at the start of the year.

Are part-time employees entitled to annual leave in Slovenia?

Yes. Part-time employees are entitled to four weeks of leave measured against their actual working pattern. A three-day-week worker, for example, is entitled to four weeks of leave (12 working days for that schedule).

Can annual leave be carried forward in Slovenia?

Annual leave should be taken within the calendar year in which it is granted. Carry-over is permitted in specific circumstances — most commonly where the employee was unable to take leave because of illness or other justified reasons. Routine carry-over is not the operating model the Act intends.

What happens to unused leave when I leave my job in Slovenia?

Untaken accrued annual leave must be paid out in cash on termination, calculated against the employee’s average earnings. This is a statutory right and cannot be waived in the employment contract.

How is annual leave pay calculated in Slovenia?

Holiday pay is calculated against the employee’s average earnings, including regular pay components the employee would normally receive for performing their role. The employee must not be financially worse off for taking statutory leave.

Do collective agreements add to the statutory four weeks?

Yes — frequently. Collective agreements in Slovenia often add days for parents, older workers, employees with a disability, and those working in hazardous conditions. Audit the kolektivna pogodba that applies to your sector or company before finalising your leave policy.

Practical Compliance Checklist

If you operate in Slovenia, your leave management system needs to handle the following at minimum:

Apply at least four weeks of statutory annual leave per employee, scaled to actual working pattern.
Layer in any additional days required by the applicable collective agreement.
Run first-year pro-rata accrual at one twelfth per completed month, switching to full entitlement from the second calendar year.
Calculate holiday pay against average earnings, including regular allowances and performance components.
Allow leave to be taken within the calendar year and avoid routine carry-over.
Pay out the cash equivalent of untaken leave automatically on termination.
Maintain auditable leave records for inspection by Slovenian labour authorities.

How Leave Balance Helps Employers in Slovenia Stay Compliant

Managing the ZDR-1 correctly across a Slovenian workforce — alongside teams in the UK, Germany, France, or the wider EU — is the kind of compliance work that breaks generic spreadsheets. Country-specific entitlement floors, collective agreement overlays, and pro-rata accrual rarely fit out of the box in a global HRIS.

Leave Balance gives you:

Country-specific entitlement rules for Slovenia, including the four-week / 20-working-day floor.
Schedule-aware leave budgets that scale automatically for part-time and atypical working patterns.
First-year pro-rata accrual that switches cleanly to full entitlement from the second calendar year.
Termination payout automation so the cash equivalent of unused leave is calculated correctly by default.
Multi-country support with separate policies per entity, all on a single dashboard.
