Cross-Appeal Dismissed for Failure to Timely Challenge Work Certificate

The court dismissed the cross-appeal because the appellant failed to timely challenge a work certificate issued during the first-instance proceedings, thereby forgoing their right to appeal on that matter. The reasoning was that since the certificate was issued after the initial claim, the appellant was obligated to substantively contest its content before the Labor Court to preserve their rights; by remaining silent, the appellant procedurally accepted the issued certificate as fulfilling the original claim regarding the certificate, regardless of whether an extrajudicial settlement was reached.
