The Challenge
One of our clients, who had previously posted employees on Polish contracts due to an increase in the scope of assignments in Switzerland, urgently needed to change the way they operated their business. In addition to the challenges of establishing a company in Switzerland, employment policies also had to be adapted.
Some employees had to be hired in Switzerland overnight, while others remained under the Polish company.
Our Solution
- Payroll compliance: We assisted with salary calculations in line with cantonal requirements, registered employees with the health insurance fund, and facilitated the selection of insurance providers.
- Work permits and banking: We supported the client in obtaining residence permits for assignments exceeding 90 days per year and in opening Swiss bank accounts for employees.
- HR and contract coordination: We helped the company implement systems for supervised access to assignments and ensured proper coordination of employment contracts.
- Crisis management: In situations requiring intervention, we liaised with Swiss authorities to resolve issues related to changes in employee status, such as tax reporting adjustments and vehicle registration.
The Result
Thanks to ATCA’s expertise, the company successfully adapted its operations and employment policies to Swiss requirements, avoiding legal pitfalls and ensuring uninterrupted business activity.
