Supreme Court dismissed appeal; employee's duty to cooperate with employer regarding sick leave misuse overrides passport refusal.

The Supreme Court dismissed the cassation appeal filed by an employee against his dismissal for allegedly misusing sick leave to travel. The court held that an employee has a statutory duty to cooperate with the employer to verify the proper use of sick leave, even if the employer's request for a passport was procedurally flawed. Consequently, the employee's refusal to provide explanations regarding his whereabouts during the sick leave period constituted the valid ground for termination.
