If your company is based in an EC/ESLA state and you wish to post employees who provide cross-border services during the exhibition, or if you are an independent service provider, you must make an online notification at least 8 days before the start of the activity.
This also applies to assembly and dismantling work, which must be notified by the company carrying out the work, be it the exhibitors themselves or a company commissioned by them (in this case, the company in question will be responsible for completing the notification). Notification procedure for short-term gainful employment
The notification procedure can be found on the federal authority website: www.sem.admin.ch
ArteCasa Management cannot be responsible for making such notifications on behalf of the foreign employer or self-employed person present at the Exhibition and declares itself in no way liable for information entered by the exhibitor.
