Question juridique clé
Whether the cantonal court violated the right to be heard by not addressing abuse of rights.
Solution extraite
No. The abuse-of-rights argument was immaterial because merely accepting a lower wage for years does not, by itself, establish a characterized abuse of rights in this context.
Motifs extraits
An authority may limit itself to relevant issues. The alleged abuse claim was too weak to matter, especially under the restrictive case law on wage claims linked to foreign-worker authorization.
