Kernrechtsfrage
Whether Art. 82(5) L-GAV 92 applied to overtime proof for the employee
Extrahierter Entscheid
The special burden-of-proof rule of Art. 82(5) L-GAV 92 did not apply because that provision was not generally binding; only the generally binding parts of the collective agreement could apply.
Extrahierte Begründung
A collective agreement binds only associated employers and employees unless declared generally binding. The employee’s membership or accession was not established, and the burden of proving applicability of the non-general binding rule rested on the plaintiff.
