Yes - you can employ your employees in different locations. To ensure that accident insurance coverage is guaranteed, the place of work should be explicitly stated with the according address in the description of the working contract.
Attention !
If the work locations are not in the same canton, you must set up separate contracts in your customer area, because the settlement with the compensation office is made per canton.
Please note, however, that your domestic help is not allowed to work in private households of third parties outside your family within the scope of your employment. For this, you would need an official permit for personnel leasing.
