Questione giuridica chiave
Whether the worker could sue in Fribourg under the joinder/forum rules despite the special employment forum
Decisione estratta
The worker could in principle invoke the joinder rule, but his claims still did not justify Fribourg jurisdiction because the dispute was rooted in the employment relationship and had to be brought at the employment forum.
Motivazione estratta
The court held that the worker may rely on the general joinder rule even against a party protected by a semi-mandatory forum rule, but that in this case the claims arose essentially from the employment contract and should be treated as a unified employment dispute.
