Swiss Employment Law for Expats: Notice, Protected Periods & the Arbeitszeugnis (2026)

Switzerland pairs American-style dismissal freedom with European-style order — and the combination surprises arrivals from both directions. No unfair-dismissal jurisdiction, no statutory severance, probation measured in weeks; yet notice periods are real, sick employees are untouchable for months, every leaver is owed a career-shaping reference letter, and courts police ‘abusive’ terminations with penalty awards. This guide states the practical 2026 rules for international employees and employers: contracts under the Code of Obligations, probation and notice, the abuse and protected-period doctrines, sick pay and its insurance architecture, vacation and family leave, non-competes, overtime, and how disputes run through the conciliation-first labor courts.

What governs a Swiss employment contract?

The Code of Obligations (OR/CO) is the base layer — a liberal statute with mandatory cores (notice floors, vacation minimums, pay continuation, abuse rules) — overlaid in many sectors by collective agreements (GAV/CCT), some declared universally binding with their own minimum wages, hours, and 13th-salary rules; a handful of cantons (Geneva, Neuchâtel, and peers) add statutory cantonal minimum wages on top.

Contracts may be verbal but professional practice is written and thorough: salary and 13th, function, hours, vacation, notice, probation, non-compete, and — increasingly — remote-work and expense clauses (employers must reimburse necessary work expenses; home-office cost case law made this live).

Reading order for expats: probation length and notice schedule; bonus wording against the gratification doctrine from the payroll guide; the sickness daily-allowance insurance clause (it defines your real sick pay, below); the non-compete; and which GAV, if any, governs — because in a GAV sector, the collective text outranks the template you were handed.

How do probation and notice actually run?

Probation: the first month by default, extendable to a maximum of three months in writing — during it, either side terminates on seven days’ notice, and the protected periods below do not apply (illness instead *extends* probation by the missed days). It is the one genuinely at-will window in Swiss employment.

After probation, statutory notice runs one month (service year 1), two months (years 2–9), three months (year 10+) — always to the end of a calendar month unless agreed otherwise; contracts may extend but not undercut, and must keep the two sides symmetric. Notice must be received, not merely sent, before the month closes — Swiss HR’s famous registered-letter deadline ritual.

Garden leave (Freistellung) is common at senior exits: employed and paid through notice, released from duties — with vacation offset rules and the duty to credit replacement income negotiated case by case. Pay in lieu as an instant-exit mechanism, US-style, does not exist as such: the notice period is real time, worked or released.

What makes a termination abusive — and what are protected periods?

Abusive termination (Art. 336) covers dismissals for personality attributes, exercising constitutional rights, frustrating claims arising from employment, union activity, or — the litigated core — retaliation for good-faith complaints; sanction is a penalty of up to six months’ salary (the dismissal itself stands — no reinstatement), claimed via written objection before notice expires and suit within 180 days.

Protected periods (Art. 336c) void employer notice given during: illness or accident (30 days in service year 1, 90 in years 2–5, 180 from year 6), pregnancy plus 16 weeks after birth, military/civil service windows, and certain foreign-aid assignments. Notice given *before* the event suspends and resumes — the mechanics behind the notice-extension arithmetic every Swiss HR team runs.

Immediate termination (Art. 337) requires cause so grave that continuation is unconscionable — theft, violence, fundamental breach — applied within days of discovery; unjustified immediate dismissal owes what notice would have paid plus a penalty. Mass dismissals add consultation and notification duties (and, at scale, social-plan obligations for larger employers).

How does sick pay really work — statute versus insurance?

The statutory floor (Art. 324a) is salary continuation for a limited period scaling with service — three weeks in year one, rising by cantonal court scales (Bern/Basel/Zurich Skalen) to a few months at long service. Modest — which is why Swiss practice runs on Krankentaggeldversicherung: collective daily-allowance insurance paying typically 80% of salary for up to 720/730 days, premium-shared, replacing the statutory scheme when at least equivalent.

Your real protection is therefore the policy in your contract: check the percentage, waiting days, and duration — the difference between the statutory scale and an insured 720 days is the difference between the German and American chapters of this series, decided by one clause.

Process duties travel with it: medical certificates from day 2–3 by custom (contracts specify), insurer case management and medical examinations in long cases, and the protected-period interaction above. Accident cases route to UVG insurance instead (per the payroll guide) — different insurer, different rules, same payslip.

Vacation, hours, overtime, and family leave

Vacation: four weeks statutory (five to age 20; five is the professional-market norm), vacation pay in lieu prohibited during employment except at exit, and employer scheduling authority tempered by consultation. Public holidays are cantonal (8–15 per canton — Ticino leads).

Working time: the Labour Act caps 45 hours/week for office/industrial/retail staff (50 for others), with overtime above contract hours compensated at 125% or time off (waivable in writing for the excess up to the statutory cap — the standard cadre clause) while Überzeit above the statutory maximum keeps mandatory premiums; night/Sunday work needs permits and supplements. Senior executives sit outside the Act’s time rules entirely.

Family leave: 14 weeks’ maternity at 80% via EO (16 in Geneva; employers often top up), 2 weeks’ paternity at 80%, adoption leave, and paid short absences for family duties — lean by this series’ Dutch/UK standards, supplemented in good employers by contract. Childcare deductions and cantonal allowances soften the famously expensive Kita economics in the relocation guide.

Non-competes, disputes, and the employee’s playbook

Non-competes bind only if written, and only where the employee had access to clientele or secrets whose use could substantially harm — capped in practice at reasonable duration (rarely enforced beyond a year or two), geography, and scope; they lapse entirely if the employer gives notice without cause attributable to the employee — the Swiss twist that converts many scary clauses into dead letters at employer-initiated exits. Courts moderate rather than void; paid-compensation clauses strengthen enforceability.

Disputes run conciliation-first at labor courts: free proceedings below CHF 30,000, no cost-shifting at that tier, and pragmatic judges — wage claims, Zeugnis wording, abusive-termination penalties, and overtime are the staple docket. Limitation discipline matters (the 180-day abusive-dismissal suit window above; five years for wage claims).

The employee playbook this series keeps rediscovering, Swiss edition: everything in writing, registered post for anything with a deadline, interim Zeugnisse collected, the insurance clauses read before you need them — and for permit holders, the immigration overlay from the work-permit guide managed in parallel, since RAV registration after job loss is both the benefit gateway and the renewal evidence.

What duties do employees owe — and how do data and monitoring rules run?

The Code’s reciprocal duties: diligent performance, loyalty (fidelity extends to side-job limits — secondary employment needs care where it competes or impairs performance), confidentiality outlasting employment for genuine secrets, and compliance with reasonable directives — the base against which warnings and immediate-termination cause are measured.

Data protection modernized with the revised FADP: employee data processed only as needed for the employment relationship, monitoring proportional and transparent (continuous surveillance of behavior is prohibited by ordinance — a line stricter than the US chapter’s norms), and cross-border HR transfers to group systems needing adequacy or safeguards — the compliance seam multinationals route through their Swiss counsel.

Whistleblowing sits in case-law limbo: internal-first escalation doctrine, retaliation feeding abusive-termination claims, and no comprehensive statute despite repeated parliamentary attempts — document internally, escalate proportionately, and take advice before going external; the six-month penalty cap from Art. 336a is the realistic remedy landscape.
