Question juridique clé
Whether the employee proved entitlement to payment for overtime hours under the CCL and Art. 8 CC / Art. 321c CO.
Solution extraite
The overtime claim fails because the employee did not timely notify the employer of the overtime and thus cannot rely on the evidentiary облегчение of the CCL.
Motifs extraits
The employee worked overtime unknown to the employer, never showed that the employer knew or should have known, and regularly signed the employer's work-time sheets without objection; this amounted to a waiver of remuneration.
