Question juridique clé
Whether the employer's joint appeal was admissible insofar as it did not seek a worse outcome for the appellant
Solution extraite
The joint appeal was inadmissible because it did not aim to modify the cantonal judgment to the detriment of the main appellant.
Motifs extraits
A joint appeal under Art. 59(2) OJ must seek reform of the judgment against the main appellant; mere confirmation or procedural criticism is insufficient.
