Construction (CN)
Convention collective de travail (CCT) · extended
The national convention for the main construction sector. Enter a working week and see instantly whether it stays within the rules, triggers overtime, or breaches a limit.
Who this agreement covers
The national construction agreement (CN) covers Switzerland's main building and civil-engineering trades: site workers, masons, formworkers, machine operators and foremen on construction and infrastructure projects. Its defining quirk is an annual hours account running from -20 up to +120 hours, which lets employers bank and draw down hours across the year to smooth seasonal peaks, so overtime is measured against the 41.75-hour reference week only once the account limits are reached, with Saturday work carrying its own 25 percent premium.

These are the limits the checker uses for this agreement.
How overtime and hours work
The national construction agreement (CN) sets a reference week of 41.75 hours, managed through an annual hours account running from -20 up to +120 hours. Hours beyond the reference week are overtime, paid at a flat 25 percent premium, with Saturday work also carrying a 25 percent premium. Switzerland's Labour Act caps the week at 50 hours, including as a 12-week average. A working day may reach 13 hours within a 13-hour span, and employees are entitled to at least 11 hours of daily rest and 35 hours of weekly rest.
A 47.75-hour week under the CN
A site worker puts in 47.75 hours during a build push against the 41.75-hour reference week. The six hours beyond the reference are overtime at the flat rate.
Hours are first tracked in the annual account (from -20 to +120 hours) before they are paid out, and the 50-hour Labour Act ceiling still applies as a 12-week average. Saturday work carries its own 25 percent premium.
Frequently asked
What is the reference working week in construction?+
The CN sets a reference week of 41.75 hours. Hours are tracked in an annual account ranging from -20 to +120 hours, which smooths seasonal peaks and troughs. Hours worked beyond the reference week are overtime, compensated with time off or paid at a 25 percent premium.
How is overtime paid on the construction site?+
Overtime beyond the 41.75-hour reference week is paid at a flat 25 percent premium, and Saturday work also carries a 25 percent premium. The weekly ceiling is 50 hours, also applied as a 12-week average, so scheduling must keep within that Labour Act limit.
What are the daily hour and rest limits?+
A working day may reach up to 13 hours of work within a 13-hour span. Employees must receive at least 11 consecutive hours of daily rest between shifts and at least 35 hours of weekly rest, in line with the Labour Act framework applied to the sector.
