Part-Time Work in Switzerland 2026: Rights, Pensions and Practice

Understanding part-time work in Switzerland requires distinguishing between the legal framework (what employers must provide), the social insurance framework (what contributions apply and when), and the practical reality of how part-time is implemented sector by sector. All three layers matter. A professional working 80% at a large bank faces a very different situation from one working 50% at an SME, even if the headline proportion is similar.

The Swiss employment rate percentage (called the "Pensum") is the standard unit. A 100% Pensum is full-time, typically 40–42 hours per week depending on the employer's collective agreement. An 80% Pensum is four days per week or proportionally reduced hours. An 80% employee working a five-day week would work approximately 32–34 hours. The Pensum affects every employment benefit proportionally, and the calculation logic is transparent in most Swiss employment contracts.

Legal rights: equal treatment and proportional benefits

Swiss employment law does not permit employers to treat part-time workers as a structurally inferior category. Part-time employees have the same legal protections as full-time employees under the Code of Obligations (OR): the same rules on termination notice, the same sick pay entitlements, the same protection against dismissal during illness or maternity, and the same access to employer-provided benefits such as accident insurance (SUVA/UVG). All of these benefits are applied proportionally to the Pensum where they are quantified in monetary terms.

Holiday entitlement is calculated proportionally. In Switzerland, the legal minimum is four weeks (20 working days at 100%), rising to five weeks for employees under 20 years old. A 60% employee is entitled to 60% of these days, but since they work fewer days per week, the calculation must account for the actual number of working days. A 60% employee working three days per week has 12 working days of holiday entitlement (60% of 20), which corresponds to four weeks of their personal working schedule. Most Swiss employment contracts specify this clearly.

Sick pay rules under the OR provide for at least three weeks of continued salary in the first year of employment, escalating on the Berner Skala or Zürcher Skala depending on the canton. Many Swiss employers supplement this via a Krankentaggeld (daily sickness allowance) insurance. Part-time workers are covered by this insurance on the same terms as full-time workers, with the daily benefit calculated based on their actual salary.

The BVG threshold: the most important number in part-time planning

The BVG (Berufliche Vorsorge, or second pillar / occupational pension) is Switzerland's employer-tied pension system. It provides retirement income that, combined with the AHV (first pillar), is designed to replace approximately 60% of pre-retirement income. The system is compulsory for employees earning above a certain annual threshold, but that threshold creates a significant gap for part-time workers.

In 2026, the BVG entry threshold (Eintrittsschwelle) is CHF 22,680 per year with a single employer. An employee earning less than this annual amount from a single employer is not required to be enrolled in the employer's pension fund. For a part-time employee working 50% at a salary of CHF 40,000 full-time equivalent, the actual annual salary is CHF 20,000, below the threshold. That employee accrues no second-pillar pension from that employer for the duration of the employment. Over a career spanning fifteen or twenty years of part-time work, this gap in second-pillar accumulation can translate to a retirement income shortfall of CHF 500–1,500 per month.

The calculation is made per employer, not per total income. This is the critical point for professionals holding multiple part-time positions. If you earn CHF 18,000 per year from employer A and CHF 18,000 from employer B, your total income is CHF 36,000, well above the BVG threshold, but neither employer is required to enrol you in their pension fund because each individual employment relationship falls below CHF 22,680. You fall through the gap entirely.

Multiple part-time jobs: consolidating BVG coverage

The Swiss pension system provides a solution for this gap, but it requires active use. The Stiftung Auffangeinrichtung BVG (the BVG safety net foundation) allows individuals with multiple part-time employers, each paying below the BVG threshold, to voluntarily affiliate and make BVG contributions based on their total combined income. This is not automatic. You must apply to affiliate, calculate your combined income, and arrange contributions. Your employers are not required to contribute to this arrangement, so the voluntary contributions are typically self-funded.

Some progressive Swiss employers, particularly larger corporates in pharma and banking, have adopted internal pension rules that apply BVG-equivalent contributions regardless of the income threshold, or that use a lower coordination deduction. If your employer has such a scheme, you may be covered even below the legal threshold. Checking your pension fund regulations (Vorsorgereglement) is essential.

AHV: no threshold, always applies

Unlike the BVG, the AHV (Alters- und Hinterlassenenversicherung, first pillar, state pension) applies to every franc of earned income regardless of the employment percentage or total annual amount. Both employee and employer contribute proportionally: the combined AHV/IV/EO rate is 10.6% of gross salary, split equally between employer and employee. There is no minimum annual income below which AHV contributions are waived. Even a CHF 5,000 annual side income from a part-time contract triggers AHV contributions, which simultaneously means you are accumulating AHV pension rights, however small.

Supplementing with Säule 3a

For part-time professionals who are not covered by a BVG pension fund, or who are covered but wish to fill the gap between their BVG accumulation and their retirement needs, the Säule 3a (third pillar) is the primary instrument. Annual contributions to Säule 3a are tax-deductible up to CHF 7,258 (for employees with a BVG second pillar) or up to 20% of net self-employment income for the self-employed. The tax deduction reduces your cantonal and federal income tax each year; the invested capital grows tax-free until withdrawal.

The practical advice for part-time workers without full BVG coverage is straightforward: maximise your Säule 3a contribution every year you work in Switzerland, invest in a low-cost equity fund (Finpension, VIAC and Frankly are the most cited digital providers), and treat this as a partial substitute for the occupational pension you are not accumulating. It will not fully close the gap, but it substantially mitigates it.

Practical landscape: which sectors offer part-time roles

Switzerland's large employers are significantly more part-time-friendly than SMEs in the same sectors elsewhere in Europe. Novartis and Roche operate formal job-sharing programmes at management and research levels. The Swiss federal administration offers 80% and 60% roles at most grades. UBS, Credit Suisse (pre-merger), and cantonal banks have long-established part-time policies, particularly for employees returning from parental leave. Public schools and universities build their staffing models around part-time arrangements at most levels.

Job-sharing, where two employees share one 100% role, is a recognised and relatively common arrangement in Swiss corporates and the public sector. It is most prevalent in project management, communications, HR and administrative roles. Some cantons have introduced internal guidelines actively encouraging job-sharing at management levels as part of gender equality policy. A job-share arrangement requires clear written protocols between the two partners and explicit employer support to function well, it is not simply two people splitting shifts.

There is no statutory right in Switzerland to reduce your hours once you are employed full-time. Unlike France, which provides a legal framework for requesting reduced hours in certain circumstances, Swiss employment law leaves this entirely to individual negotiation. Your employer can decline your request to move from 100% to 80% without legal consequence. In practice, Swiss employers, especially large ones, are often willing to accommodate such requests to retain talent, but there is no legal lever if they refuse.

Salary calculation and payslip logic

Salary for part-time work in Switzerland is always expressed as a proportion of the full-time equivalent (FTE). A role advertised as "CHF 100,000 à 80%" pays CHF 80,000 annually, or CHF 6,667 gross per month if on a 12-month contract (or CHF 6,154 per month if a 13th salary is paid, giving CHF 80,000 over 13 payments). Social deductions, AHV, IV, EO, ALV, NBUV (accident insurance for non-occupational accidents), and BVG where applicable, are all calculated on the actual earned salary, not the FTE equivalent. Your payslip will show each deduction as a percentage of your Pensum-adjusted gross, not the theoretical full-time figure.

Frequently Asked Questions

Do part-time workers have the same rights in Switzerland?

Yes. Swiss employment law treats part-time workers identically to full-time workers for all core protections: termination notice, sick pay, accident insurance, maternity protection and anti-discrimination rules. Benefits with a monetary value, holiday days, sick pay entitlement, salary continuation, are calculated proportionally to the Pensum. There is no legal category of "temporary" or "secondary" status attached to part-time employment under Swiss law.

What happens to pension contributions if I work part-time in Switzerland?

AHV (first pillar) contributions apply at any income level with no threshold. BVG (second pillar) contributions are only mandatory if your annual income from a single employer exceeds CHF 22,680. Below this threshold, which catches many part-time and multiple-employer situations, you accumulate no occupational pension from that employer. The gap should be partially addressed through voluntary Säule 3a contributions and, where available, voluntary affiliation to the Stiftung Auffangeinrichtung BVG.

Is there a legal right to work part-time in Switzerland?

No. Unlike France, Switzerland has no statutory right to request reduced hours. If you are currently employed full-time and wish to move to a part-time arrangement, this is a matter of negotiation with your employer, who can decline without legal consequence. In practice, large Swiss employers often accommodate such requests to retain experienced staff, particularly after parental leave, but the decision rests entirely with the employer.

How is holiday entitlement calculated for part-time workers in Switzerland?

Holiday entitlement is calculated as a proportion of the full-time entitlement (minimum four weeks / 20 working days), adjusted for the Pensum. A 60% employee has 60% of 20 working days = 12 days of holiday, measured in their actual working days. Because they work fewer days per week, this still corresponds to four full weeks of personal schedule. Employment contracts usually specify this explicitly; if they do not, you can calculate it from the Pensum percentage.
