Supreme Court dismissed cassation; unauthorized refusal to obey work order constitutes serious breach justifying dismissal.

The Supreme Court dismissed the cassation appeal filed by a paramedic against his dismissal for refusing a work order. The plaintiff argued the order was unauthorized and outside his duties, while the employer contended it endangered patient safety and constituted a serious breach. The court ruled that the refusal was a conscious violation of a lawful duty, creating a grave risk to medical staff and patients, thus validating the employer's decision.
