Employment Contract: Working Hours and Overtime Clause
A working-hours clause sets weekly Pensum, daily schedule, and overtime rules. Swiss law (OR Article 327c) requires reasonable working time; you must specify hours and compensation method. Disputes arise when overtime expectations are implied but not documented, or when compensation method conflicts with GAV standards.
The working-hours clause is one of the most frequently negotiated parts of a Swiss employment contract. It defines the employee's weekly or monthly Pensum percentage, daily and weekly schedule, and how overtime is handled and paid. Without clear terms, both employer and employee risk misalignment on expectations.
Swiss employment law (Obligationenrecht) does not set a fixed maximum working week, but Article 327c requires hours to be reasonable and agreed in writing. Most Swiss cantons and industry GAVs inform what is typical—often 40–42 hours weekly for office roles, 41–43 for trades.
What the Clause Must Cover
State the Pensum percentage (80%, 100%, 120%) or absolute weekly hours. Include standard daily start and end times, or note flexibility (e.g., core hours 09:00–12:00 and 14:00–17:00). Specify whether the role involves irregular or on-call work.
Document how overtime is recorded, approved, and compensated. Common methods include time-in-lieu (Zeitausgleich), lump-sum honorarium, or hourly surcharge. Clarity here prevents disputes about unpaid work.
- Pensum as percentage or absolute hours per week
- Daily start/end times or flexible/core-hours model
- Definition of what counts as overtime (hours beyond stated Pensum)
- Approval process for overtime (who authorizes, how documented)
- Compensation method (time-in-lieu, lump sum, or hourly rate)
- Any role-specific exceptions (e.g., on-call availability, travel)
Swiss Law and Reasonable Defaults
OR Article 327c requires working time to be reasonable and defined in the contract. There is no statutory maximum, but cantonal and sector GAVs provide benchmarks. For example, Zurich's commercial GAV typical sets 40 hours; retail often 42. Always check your canton and industry.
A reasonable default for office roles is 40–42 hours per week, 100% Pensum. Overtime beyond this is typically compensated at time-in-lieu (1:1 or 1:1.25) or a small surcharge (10–20%). Some employers use a lump-sum monthly allowance for minor overtime; others require explicit approval and tracking.
- No statutory maximum, but cantonal/sector GAV applies
- Most office roles: 40–42 hours/week at 100% Pensum
- Trades and logistics often higher: 41–43 hours
- Time-in-lieu (Zeitausgleich) is most common compensation
- Surcharge method requires clear hourly rate agreement
- Lump-sum allowance only if minor and consistent
Common Disputes and How to Avoid Them
The biggest dispute: employer expects unpaid overtime as "normal" for the role, but contract says 100% Pensum with no overtime clause. Employees later claim constructive variation of terms or unpaid work. Always document what is expected.
Second common error: stating "overtime as needed" without defining compensation. Swiss labour courts assume time-in-lieu 1:1 unless contract says otherwise. If you prefer lump-sum, state the CHF amount and make clear it covers all overtime. Get legal review if unsure of your canton's norms.
- Implied overtime (not in writing) leads to disputes and wage claims
- "Overtime as needed" without compensation method defaults to time-in-lieu 1:1
- Lump-sum allowances must be explicit and reasonable under local GAV
- Pensum inflation: employee hired at 80%, gradually expected at 100% unpaid
- On-call/standby work must be separately defined and compensated
- Changes to hours require written agreement and often statutory notice
Frequently asked questions
- Can I ask an employee to work 50 hours one week without extra pay?
- Only if the contract explicitly permits flexible or higher Pensum, or if time-in-lieu is agreed. If contracted at 40 hours, 10 extra hours typically require compensation (time off or surcharge). Check your canton's GAV; some set limits on weekly or monthly overtime.
- Is time-in-lieu (Zeitausgleich) legally binding?
- Yes, if agreed in the contract. The standard is 1:1 (one hour overtime = one hour off). You may offer 1:1.25 to make it attractive. However, time must be taken within a reasonable period (usually within the same month or quarter). Consult a lawyer on your canton's rules.
- What if I pay a lump sum for overtime—is that enough?
- Only if the amount is clearly stated in the contract and reasonable under your canton's GAV and industry standards. If later disputes arise about actual overtime hours, courts may find the lump sum insufficient. Document how you arrived at the figure and review it annually.
