Supreme Court dismissed cassation, upholding lower court's finding of serious breach of duty justifying immediate dismissal.

The Supreme Court dismissed the cassation appeal filed by the employer against the lower court's decision to dismiss the employee without notice. The lower court found that the employee's failure to terminate a prior employment contract with a competing firm constituted a serious breach of duty, warranting immediate termination. The Supreme Court agreed, ruling that the employer failed to prove the new employment negatively impacted the business or that the employee breached duties, thus upholding the dismissal.
