The Swiss Cantonal Labour Inspectorates have the authority to request various documents from employers to verify compliance with the working and wage conditions. These documents must be provided in an official language and may include:
Employment Contracts: Copies of the contracts between the employer and the posted workers, detailing the terms and conditions of employment.
Payroll Records: Documentation of wages paid to the workers, including any supplements and deductions.
Proof of Social Contribution Payments: Evidence that the employer has made the required social security contributions for the posted workers.
Records of Working Hours and Rest Periods: Logs or records showing the hours worked by the posted workers and their rest periods.
Workplace Safety and Health Documents: Records related to workplace safety measures, health checks, and hygiene standards maintained at the worksite.
Employers must also grant the Labour Inspectorate access to workplaces and administrative premises at all times for inspection purposes.
