Questão jurídica principal
Whether the dismissal was abusive under Art. 336 CO because it allegedly punished diligent performance or was otherwise pretextual.
Decisão extraída
The appellant failed to show that the employer's stated reasons were a mere pretext; the established reasons were poor performance and excessive delegation, so the dismissal was not abusive.
Fundamentação extraída
The cantonal findings on the reasons for termination bound the Court, and the appellant offered only an appellatory version of the facts without demonstrating arbitrariness or legal error.
