Unpaid Leave (Unbezahlter Urlaub)
Unpaid leave is time away from work without compensation. It differs from paid vacation (Urlaub), which is a statutory right in Switzerland. An employer and employee must agree in writing before granting unpaid leave. It cannot reduce or replace the mandatory paid vacation days set by the ArG or a GAV.
Unpaid leave is an absence period during which an employee receives no salary. It is distinct from paid vacation (Urlaub), which Swiss law guarantees as a minimum right. Unpaid leave only exists if both parties agree—usually in writing—and must never substitute for statutory paid days.
You may encounter unpaid leave requests for sabbaticals, extended caregiving, retraining, or personal projects. The Swiss Code of Obligations (ArG) sets minimum paid vacation (4 weeks for most roles); unpaid leave sits outside this floor and must be negotiated separately.
When unpaid leave comes up
Unpaid leave typically arises when an employee needs time beyond their paid vacation allowance—for parental care, illness not covered by insurance, a sabbatical, or relocation preparation. It is not automatic and requires your explicit consent.
Common scenarios include maternity/paternity gaps (if not covered by cantonal law or GAV), career breaks, or travel not fitting paid days. Each request should be treated as a separate negotiation.
- Parental or caregiving responsibilities beyond statutory protection periods
- Sabbaticals or extended personal projects
- Professional retraining or certification outside work hours
- Relocation or immigration paperwork requiring extended absence
- Illness periods exceeding sick-leave coverage or waiting periods
- Written agreement is mandatory; no verbal consent suffices
Your employer obligations
Swiss law (ArG Article 20) mandates at least 4 weeks of paid vacation annually. Unpaid leave is entirely optional and must be documented in writing. You can refuse it, but fairness and retention often favour considering reasonable requests.
If you grant unpaid leave, document the duration, start/end dates, and whether it affects benefits (insurance, pension contributions) or re-integration terms. Ensure the agreement specifies whether unpaid days extend the employment contract or count toward seniority.
- Protect minimum paid vacation entitlements—never let unpaid leave replace them
- Get written agreement signed by both parties before the absence begins
- Clarify impact on health insurance, AHV/ALV contributions, and benefits
- Specify re-entry date and any probation or adjustment period
- Document in your personnel file for future reference and consistency
- Check your cantonal rules and GAV (if applicable) for special cases (e.g. family support)
The most common mistake
Many employers treat unpaid leave informally—a casual 'take a few weeks' without writing it down. This creates disputes about pay, insurance status, and re-entry expectations later. A verbal agreement is unenforceable and risky.
The second frequent error is assuming unpaid leave can substitute for paid vacation. If an employee has 20 vacation days left and you offer 10 unpaid days instead, you are breaking the ArG. Paid days must be granted separately and used or compensated before termination.
- Verbal agreements on unpaid leave lead to misunderstanding and disputes
- Failing to distinguish unpaid leave from paid vacation violates the ArG
- Not documenting insurance or pension contribution status during absence
- Forgetting to clarify whether unpaid time counts toward notice periods or severance
- Allowing unpaid leave to drag on indefinitely without a firm end date
- Overlooking cantonal paid leave rules (some exceed 4 weeks) when negotiating unpaid time
Frequently asked questions
- Can I deny an unpaid leave request?
- Yes. Unpaid leave is not a legal right—it requires mutual agreement. You may refuse on business grounds. However, rejecting reasonable requests for family care or emergencies may affect morale and retention. Document your decision.
- Does unpaid leave count toward seniority or severance?
- Not automatically. The written agreement must specify whether the unpaid period extends the employment contract or pauses it. If you want it to count toward seniority, say so in writing. Otherwise, it is a gap with no impact on service length calculations.
- What happens to insurance and pension during unpaid leave?
- Health insurance (LAMal) and obligatory pension contributions (BVG) usually continue—the employee or employer may pay their share depending on your agreement. Some cantons have different rules. Confirm with your benefits provider and insurer before granting unpaid time.
